JoinMap 4 Release notes
=========================


=== 19 Februay 2010 ===
Maintenance release of JoinMap 4
  (Build: 19feb10.9feb10)

= Creating a population node of a CP type dataset node
  resulted in an error. A similar bug resulted with the
  exporting as loc-file from Data tabsheets in minor
  errors in the loc-file. The bugs were repaired. 


=== 16 Februay 2010 ===
Maintenance release of JoinMap 4
  (Build: 16feb10.9feb10)

= To make working with large marker datasets of a population
  a bit faster, new options are introduced:
  -A checkbox option on the tool bar controls whether or not
  the various Data tabsheets are loaded; it can also be set
  in the Options-menu.
  -Large datasets create huge tables of pairwise linkages
  and if they are not going to be inspected things are
  faster if the tables are left out altogether. Therefore,
  in the Group tabsheet of the calculation options two new
  checkboxes control whether or not weak and strong linkages
  tables are created when the linkages are calculated.

= The Colorize function to show graphical genotypes now
  takes the linkage phases into account (if available) for
  all segregation types except <hkxhk>. For instance,
  genotype lm of a marker with phase {1-} is shown in the
  same color as genotype ll of a marker with phase {0-}. The
  default colors are modified for a better correspondence
  between the segregation types.

= An option is added that controls whether the current
  selection or the entire tabsheet contents must be printed,
  copied, or exported; it is a check box on the tool bar and
  is also available in the Options-menu.

= The Highlight Errors function now also allows
  classification types (a,h) and (h,b) for population types
  BCpxFy. And when the y-generation is zero (i.e. it is a
  normal BC1), only genotypes a and h (BCAxFy), or h and b
  (BCBxFy) are allowed.

= With an added option in the Help-menu you can now check
  via the internet whether a newer release is available.
  If your internet connection requires the use of a proxy,
  you can supply the proxy name and port in the environment
  options.

= Several internal actions that may take a while now change
  the cursor temporarily into the hourglass cursor.

= Map-files or pwd-files in which the comma is used as
  decimal separator (instead of the point) will be loaded
  correctly.

= Maps with multiple linkage groups are now inverted
  group by group with the Invert Map function of the
  Map-menu.

= The time stamp now also shows the seconds.


=== 11 August 2008 ===
Maintenance release of JoinMap 4
  (Build: 11aug08.7apr08)

= In the ML mapping algorithm the fixed order was not always
  maintained; this is corrected.

= The tabsheet with the Locus Means of the Genotype
  Probabilities is sorted on the map position of the loci.
  This will result in a proper chart when plotted against
  the map position.

= The tabsheet with the Individual Means of the Genotype
  Probabilities is given in the original order of the
  individuals.


=== 23 July 2008 ===
Maintenance release of JoinMap 4
  (Build: 23jul08.7apr08)

= If the grouping cannot be calculated for a population
  type CP, better information will now be shown.

= The situation with three (or more) loci at the same map
  position could lead to a floating point error in the ML
  map calculations. This is corrected.

= The cooling control parameter of the ML Mapping algorithm
  had a lower limit of 0.001 which is now reduced to
  0.00001; the upper limit is now set to 1.0.

= The tabsheet with the Locus Means of the Genotype
  Probabilities now also shows the map position of the loci.

= When no project is open, pressing the OK button on the
  Environment and the Calculation Options dialogs will save
  the options as default options that will apply to all
  future projects (similar to the 'Save as default' button).
                 
= The About box was renewed.


=== 8 April 2008 ===
Maintenance release of JoinMap 4
  (Build: 8apr08.7apr08)

= For a BCpxFy the genotype probabilities given the map
  given two heterozygous or dominant flanking markers were
  not completely right. This is corrected.

= The map chart options dialog can be opened when no map
  chart is visible; changing the options will have the same
  effect as 'Save as Default Map Chart Options'. Any future
  map chart will be drawn according to these options. 

= Also, when no map chart is visible the 'Reset to Preset
  Map Chart Options' can be activated, which will affect
  all future map charts. 

= The loading of MAPMAKER raw data is slightly improved.

= Various minor (internal) improvements were made.


=== 4 May 2007 ===
Maintenance release of JoinMap 4
  (Build: 4may07.4oct06)

Changes:
= JoinMap 4 was enabled to run under Windows Vista.
  For installation of the user license under Windows Vista,
  please see the 'Installation ReadMe' file on the CDROM or
  in the program directory after running the program 
  installation 'setup.exe' 
  (typically: 'C:\Program Files\JoinMap4').


=== 18 April 2007 ===
Maintenance release of JoinMap 4
  (Build: 18apr07.4oct06)

Changes:
= When exporting the Data tabsheet of a Map node of a CP
  type population as a loc-file, the map position of 
  markers was given at the wrong place in the file.
  This is corrected.

= The exporting of a Dataset tabsheet of a Dataset node as
  a loc-file did not function properly. This is corrected.


=== 5 March 2007 ===
Maintenance release of JoinMap 4
  (Build: 5mar07.4oct06)

Changes:
= When calculating the linkages for groups of population
  type CP, it is possible that the linkage phases cannot
  be determined and thus also no recombination frequencies
  can be calculated. In such instances the program could 
  generate an unclear runtime error message: 'unknown error
  in sclastype()'.
  This problem is corrected and the information given in
  the 'Info on Tabsheet Contents' has become more complete
  about the linkage phases determination status.


=== 4 October 2006 ===
Maintenance release of JoinMap 4
  (Build: 2oct06.4oct06)

Changes:
= For extremely large values of the chisquare distribution
  the P-value in the Grouping tabsheet could not be
  calculated and resulted in the freezing of the program.
  The P-value is calculated irrespective of the Grouping
  parameter chosen.

  A new algorithm to calculate the P-value is now used.

= For very large linkage groups the computations of the
  linkages may appear to take extremely long. Actually,
  it is not the computations that take a long time but
  the loading of the resulting data into the Linkages
  tabsheets. For such large linkage groups there may
  be very, very many pairs to display on the Weak and
  Strong linkages tabsheets, depending on the chosen
  corresponding thresholds.

  To allow for more precision here, the recombination
  frequency thresholds on the Group tabsheet of the
  Calculation Options now have up to four decimals.

  Unfortunately the loading of the data into the
  tabsheets cannot be shown on the progress bar, but the
  progress of the program is now shown with some simple
  comments on the status bar:
    'loading table "Weak Linkages"'
    'loading table "Strong Linkages"'
    'loading table "Suspect Linkages"'
  together with the numbers of rows that must be loaded,
  allowing the user to see and estimate the progress.
  These comments are usually only visible with very large
  groups.
