Hi Bruce, Tried the downloading the mris_convert from surfer.nmr.mgh.harvard.edu:/space/outgoing/fsdev and again doing:
mris_convert -c ./lh.area lh.orig lh.area.asc (after renaming the old lh.area.asc file). However the output is the same, as far as I can tell. Here are the first 8 lines of the newly created lh.area.asc file: 000 -9.50000 -97.50000 -23.50000 161.92000 001 -10.50000 -97.50000 -23.50000 0.00000 002 -11.50000 -97.50000 -23.50000 163.20000 003 -7.50000 -97.50000 -24.50000 0.00000 004 -8.50000 -97.50000 -24.50000 162.88000 005 -9.50000 -97.50000 -24.50000 0.00000 006 -10.50000 -97.50000 -24.50000 162.88000 007 -11.50000 -97.50000 -24.50000 0.00000 Still has 0.00000 on every other line. Clearly something is wrong. Any ideas what might be the trouble, and/or what we could try next? Also, what are the units for these average area numbers? I assume they are very small. -Tom On Thursday, June 13, 2002, at 07:46 PM, Bruce Fischl wrote: > you should convert the patch to ascii using mris_convert -p and get the > vertex #s from the ascii file.
