 2.0.23 (2017-03-27) - The markers file input is now optional - if omitted, pseudo-markers will be
generated to satisfy GISTIC's input requirements while ensuring reasonably
uniform coverage of the genome.
- The "broad analysis" of arm-level events has been revised:
(1) arm-level events are now called from a single broad copy number profile
instead of separate amplification and deletion profiles, which had led to
arms counterintuitively called as amplified and deleted on the same sample;
(2) the frequency scores used to determine z-scores and q-values, which excludes
arms with the opposite call from the denominator, are now in a column called
"frequency score". A new column called "frequncy" gives the intuitive frequency
with the denominator inluding arms from all the samples. The analysis results
for the same data will be different from that of previous GISTIC versions.
- Error handling messages have been improved. In particular, many informative
error messages were masked by an "Index exceeds matrix dimensions" error
in the exception handler itself.
- An hg38 reference genome is included with this release.
- The gp_gistic2_from_seg binary executable is now compiled for MCR 8.3
(Matlab R2014a). The source code is compatible with versions of Matlab up to
R2016a, however, the appearance of output graphics may be altered for Matlab
versions R2015a and later.
- This release adds the convenient 'gistic2' wrapper function which sets up
the MCR and passes its command line argument to the executable. Scripts have
been converted from the C-shell to the Bourne shell.
