MapDisto change log

Versions 2.0 beta
2.0 beta 2.0 beta 1 to 26

* Feature: compute RF & LOD in R/qtl can now find linkage groups
* Option to avoid writing RF & LOD matrix on disk in compute RF & LOD in R/qtl
* “Detailed map”, “Draw map”, Write map” commands now handle dominant markers (although dominant markers in repulsion are still an issue and this case should be avoided for now). Useful to map dominant, monogenic phenotypic traits on a map of codominant markers. [I still need to extend that to all procedures, like “Find groups”, “Matrix group”, etc…)
* changed p to -log10(p) in Khi2group procedure.
* Feature: R/qtl basic interface (Mac only for now)

2.0 beta 28
New features
* Feature: New “Convert VCF to data” feature in the ‘Data’ window
This is allowed by a new Java module by Chris Heffelfinger (S. Dellaporta’s lab, Yale University), that allows to import VCF files from Genotyping-by-Sequencing experiments into MapDisto from the ‘Data’ window. The Java program prepares a Mapmaker/EXP .raw compatible file that can be imported back in MapDisto unsung the ‘Import…’ command in the ‘Data’ window.
Note: The MapDisto.jar .vcf file has to be in the running copy of MapDisto.
Note: You will need to install the Java JKD installed (In a near future use of the standard Java RTE will eliminate this)
* Feature: New “Export data to R/qtl” feature in the ‘Data’ window.
Note: Don’t forget to choose the .csv file type before saving the file.
* Feature: New “Prepare imputation in /qtl” feature in the ‘Data’ window (uses the argmax R/qtl command).
This prepares a .Rmd file that can be run from within RStudio
Note: You will need to install RStudio, R and the R/qtl package.
* Feature: New “Drop locus summary” feature in Drop locus window.
* Feature: New “Create summary” feature in Framework map window.
* Feature: New fast Copy/Paste/Paste Transposed buttons in the MapDisto Toolbar. Useful for manipulating large matrices – the Excel 2011 built-in Copy/Paste gets very slow for large data tables.

* Improvement: Handles more than loci 32,768 (changed all Integer variable types to Long).
* Improvement: Much faster “Remove locus” command in the Main window.

Bug fixes
* bug: “Bad population type” message while importing MMK file fixed.

v. (Excel 2011 only)
* Spread some DoEvents in the code

v. (Excel 2011 only)
* Modified the 'Used these data' and 'Load data' commands (changed "Copy/paste" that was causing very long waitings to "load-data-in-array-then-write-in-sheet")

v. (Nov 1, 2011)
* Corrected a small bug in all versions that forced drawing of all LGs after running the Draw mapmaker map command.

v. 1.7.5 (Oct 31, 2011)
* MapDisto goes to version 1.7.5 final for Excel 2003, 2007 (Windows), Excel 2004 and 2011 (Mac OS X).
* New version for Excel 2010, which is virtually the same as for Excel 2007 except for some small changes in drawing maps.

v. 1.7 (October 25, 2007) - changes since v. 1.6:

* Feature: Compute stats in Color genotypes provides basic statistics on the allelic content of each genotype.
* Feature: "Data fit sequences" command will remove all the loci that are not present in the declared sequences from the Data window. Moreover, the loci will be re-numbered from 1 to l, if there are l loci declared. Also, the loci will be re-ordered in the Data window according to the order their appear in the declared sequences.
* Feature: Two new algorithms for marker ordering were implemented:
    * the Unidirectional Growth (Tan and Fu, Genetics 173: 2383–2390 - August 2006)
    * an improved version of the Branch & Bound algorithm, that seems to outperform the Unidirectional Growth and the seriation algorithms. (The seriation method was the first one implemented in MapDisto.) This new algorithm was tested on both simulated and real data and is very promising.
* Feature: A powerful method to improve the marker order found with one of the three algorithms available, called "Check inversions". The command will repeat the inversion procedure on all linkage group until their order is stable.
* Feature: An automatic implementation of the Ripple command, called "AutoRipple", to easily run the Ripple command on all linkage groups. The command will repeat the Ripple command until it finds the best order.
* Feature: A procedure to iteratively correct the data errors (inspired by the SMOOTH algorithm, van OS et al, Theoretical and Applied Genetics 112:187-194 - 2005). This procedure is still under testing and it should not be used for publication purpose.
* Feature: A "Three point" command, that allows to check the LOD scores for all the three-point orders of a given sequence.
* Feature: A command to remove the loci that are not assigned to a sequence. This command will also re-order the loci within the data file according to their location in the sequences.
* Feature: Color genotypes, to easily visualize and/or replace/remove the double recombinations, the candidate erroneous data points and the missing data.
* Feature: In "Options", one can uncheck the "Ripple is progressive" checkbox to get an output more similar to that of Mapmaker/EXP.
* Feature: Added the COUNT criteria for the Seriation algorithm (van OS et al, Theoretical and Applied Genetics 112:30-40 - 2005).
* Feature: Added a modified version of the CorrSum criteria for the Seriation algorithm (inspired by the criteria used in the Macintosh version of Mapmaker).
    The CorrSum is (1 - r) (1 - EXP(-LOD)), where LOD is a normalized LOD score.
    LOD = LODscore * (N / n), where n is the number of informative meioses for the pair of loci considered, and N is the total number of individuals in the population.
* Feature: A tool to graphically compare two linkage maps. The maps to be compared can easily be imported from the Main menu, Framework map, Extracted map and Simulations windows. One can also import a map from a text file, provided that it is in the standard MapDisto format.
* Feature: A new recombination fraction estimate for SSD populations, based on the paper of Martin and Hospital (Genetics 173:451-459 - May 2006)
* Feature: New simulation tool.
* Feature: Option to export map and data for QTL Cartographer (not WinQTLCart, which is already available as an option).
* Feature: Maps and populations (BC1s and F2s) simulation tool.

* Improvement: The Color genotypes command is a two times faster (but still slow).
* Improvement: Better display of QTLs when using the Draw QTLs command. The legend in Draw QTLs is now clickable for fast display of the QTLs for a particular trait.
* Improvement: Some minor interface improvements.
* Improvement: In Color genotypes, the Load data command now works independently from the Framework map.
* Improvement: Importing .out Mapmaker/EXP files now works with error detection set to on or off.
* Improvement: improved the way of computing the probability of error candidates for BC1, DH, SSD and HRILx populations. F2 populations still not supported.
* Improvement: In Color genotypes, changed "Count double recombinants" to "Count error candidates".
* Improvement: Changed the way to manage error threshold in the Iterative error detection procedure and in all the Color genotype-related commands: the new threshold is now equal to (1 - old threshold).
* Improvement: Some minor interface improvements.
* Improvement: More Color Genotypes options.
* Improvement: All the criteria are now available for the Branch & Bound II algorithm.
* Improvement: The CorrSum criteria was renamed as SA Corr (Sum of Adjacent Correlations) in the Options dialog box. Moreover, one can now choose to use the original Correlation (the one used in the Macintosh version of Mapmaker).
    The Correlation is (1 - r) (1 - EXP(-LOD)), where LOD is the true LOD score.
This option is activated when the check box "Use normalized LODs" is unchecked.
* Improvement: The Branch & Bound II algorithm now works recursively and will stop only when it finds the best order according to the given criteria.
* Improvement: More simulation options (missing data, data errors, F2 and SSD populations).
* Improvement: Pre-computing of RF matrices for ordering loci is now 2 times faster
* Improvement: Much faster execution of the BatchMap command (up to 4 times).
* Improvement: More simulation options.
* Improvement: Minor improvements.

* Improvement: Simulation tool improved, with much faster AutoBatchMap and BatchMap commands. More genotypes (up to 508) allowed for BatchMap. Segregation distortion loci implemented (Backcross populations only). More comments. Option for generating semi-random marker positions. New command to display a histogram of the map sizes obtained.
* Improvement: the Import data command was re-written. It is now faster and more reliable. Also, it allows to import Mapmaker data that are not of the original format, ie, using symbols for genotypes others than A, B, C, D, H and -.
* Improvement: The main menu window interface was modified to allow locus numbers > 999 to be displayed correctly.
* Improvement: some minor things.
* Improvement: Added the two point and three point commands in the exported run file for Mapmaker/EXP when the Ripple command is included.
* Improvement: minor improvements.

* Bug fix: Some commands in Color genotypes were generating an error in case of having three (or more) co-segregating markers.
* Bug fix: Corrected a bug of double recombinant counting and display in Color genotypes.
* Bug fix: Some minor fixes.
* Bug fix: There was sometimes an error while importing .out Mapmaker/EXP files.
* Bug fix: The Replace order command was sometimes generating an error.
* Bug fix: Fixed some minor bugs introduced in the 1.7 beta version.
* Bug fix: The program was generating an error on the Mac OS X platform.
* Bug fixes: Many...

* Interface: The "Option" dialog box was slightly re-organized.
* Interface: The main menu was re-organized.

v. 1.6 (October 11, 2006) - changes since v. 1.5:

* Feature: Added a SAD (Sum of Adjacent Distances) criteria for ordering, that corresponds to the old SARF. Note that using this criteria with sequences made of a mixture of loosely and tightly linked loci may not be a good idea, and that results may vary according to the mapping function selected (Haldane or Kosambi).
* Feature: Added an option to choose the space between linkage groups in "Draw all sequences" or "Draw pre-computed map" command.
* Feature: Bootstrap and Monte Carlo procedures to estimate and verify a sequence order. One can run both procedures using the command "Bootstrap order". To choose the Bootstrap procedure only, don't check the "Reshuffle initial order" check box when you are prompted for Bootstap parameters. To choose the Monte Carlo procedure only,  check the "Reshuffle initial order" check box and enter the value "100" in the field "Subsample size". To perform a combined test (Bootstrap + Monte Carlo at the same time), check the "Reshuffle initial order" check box and choose a value of Subsample size inferior to 100 (e.g., 95).
* Feature: Command "Show assignments" to display the assignments (or non assignments) to the declared sequences of all the loci declared in the Data window.
* Feature: Command to add the sequences of the current Framework map to the My Sequences field of the Main Menu window.
* Feature: Command to check for availability of new versions.
* Feature: Command to find the closest locus to a given locus ("Place locus...".

* Feature: Command to show a graphical display of the extracted map from a database.
* Feature: Commands to open, save, import and draw the current framework map.
* Feature: Define a computed map as framework map.
* Feature: Drop locus. Useful to test the effect of removing loci one by one from a linkage group. Allows to quickly identify problematic markers. Similar to the Drop marker command of Mapmaker for Macintosh version 2.0. Note: a Perl script (written by Jean-François Rami) that adds this function to Mapmaker 3.0/EXP is available upon request from the Author.
* Feature: Exportation of Mapmaker/EXP .in file that can be launched within Mapmaker/EXP with the 'run' command.
* Feature: Extract marker positions from a personal database (a format is provided).
* Feature: F2 populations are now partially handled.
* Feature: If a new version is found at startup or as a result of the "Check version" command, a list of the last changes is downloaded and displayed.
* Feature: Importation of Mapmaker/EXP sequences (representing linkage groups).
* Feature: Importation of Mapmaker/EXP standard data files.
* Feature: Modified the SARF criteria. The SARF now really corresponds to the Sum of Adjacent Recombination Fractions (it was formerly corresponding to the SAD, or Sum of Adjacent Distances in centimorgans). The new SARF is more reliable than the old one (= SAD) when ordering a sequence made of a mixture of loosely and tightly linked loci.
* Feature: Partial handling for IRIL (Intermated recombinant inbred lines) populations.
* Feature: The Drop locus command now handles for F2 populations (codominant loci only).

* Improvement: "AutoOrder" will flip any sequence that starts with a locus number higher than the locus number it ends with.
* Improvement: "Draw QTLs" now can display marker names (Warning: QTLs with negative additivity are not displayed on the left of the chromosomes if this option is chosen).

* Improvement: in the Options dialog box, the radio box "Use absolute distances" is  activated only if the "GraphGenot" radio button is selected.
* Improvement: It is now possible to work with up to 1,000 sequences.
* Improvement: It's now possible to import Mapmaker/EXP data files that have up to 504 individuals. Works with Excel X and 2004 for Mac OS X, and Excel 2003 for Windows. Should work with Excel XP (2002). With Excel 2000, only the marker data are imported properly, QTL data are cut.
* Improvement: Many computations are faster (up to 2 times) (Except for F2 populations).
* Improvement: Many computations are faster (up to 2 times) for F2 populations.
* Improvement: More advanced saving of graphical maps & QTLs.
* Improvement: Several minor interface modifications.
