Converting from LINKAGE format to ASPEX format with Mega2
The free Mega2 software can convert from LINKAGE format to ASPEX format,
as well as to a number of other formats.
During an association or linkage analysis project, it can often be
quite difficult to get one's data in the proper format desired by
each different computer program. Not only must the data be
transformed to the proper format, but also the loci must be
reordered into their proper order. To address this problem, we
created Mega2, which can be obtained from our software
distribution site.
Mega2 greatly eases and automates the tedious error-prone process
of reformatting one's data from one format to another.
For additional information, please see the Mega2
documentation.
