Chapter 4. About Haploview
Haploview was developed in and is maintained by
Mark Daly's lab
at the Whitehead Institute by
Jeffrey Barrett and
Julian Maller.
- The design of the interfaces is the work of Ben Fry at
the MIT Media
Lab.
- Thanks to Andrew Kirby for large chunks of coding.

Abecasis and Jan Wigginton at the
University of Michigan
Center for Statistical Genetics
- The r2 and alternative D' color schemes are the work
of Will Fitzhugh.
- The interface to the HapMap GBrowse track is courtesy of
Simon Twigger.

Questions, complaints and suggestion should be directed to
Jeffrey Barrett.
It is recommended that Haploview be run on a machine with at least
128M of memory. The Haploview jarfile should now automatically
allocate extra memory when starting up, so the -Xmx flag is no longer
required when running the program from the command line.
Haploview requires Java JRE 1.3 or later, but 1.4 is strongly
recommended. It is worthwhile in any case to download the most recent Java
release.
Saving PNG files from the command line (the -png and -compressedpng
flags) requires Java version 1.4 or later.
There appears to be an issue with the Windows JDK version
1.4.1_03. Note that all other versions (both earlier and later
versions of 1.4.1 included) seem to work fine. If you find this
to be your current Java version (type java -version at the
command prompt), please install the latest version.
Windows JDK version 1.3.1_02 seems to have trouble saving PNGs
properly. Marker names are partially truncated in the saved
file. Again, installing the latest version of Java should fix this
issue.
If you have an internet connection, Haploview will automatically
check for an update upon startup. If a new version is available, it
will show a message in the lower right corner of the screen for a few
seconds. Details can be found by using the "Check for Updates" button
in the File menu.
