Hi JeeSu
if you look at the help for mris_convert, you'll see this example:
Convert a scalar overlay file in "curv" format to ascii:
mris_convert -c lh.thickness lh.white lh.thickness.asc
which you should follow
cheers

External Email - Use Caution
Hello,
I am trying to convert ascii files containing vertex-wise thickness data into
binary curvature files
for subsequent smoothing and input into mri_glmfit. The command I used is:
mris_convert lh.test.asc lh.test.thickness
But then get the following error:
ERROR: MRISalloc: nfaces=-5 < 0
No such file or directory
I'm not sure what file or directory the error message is referring to, nor what
the meaning of
nfaces is. I am running version 6.0 on macOS Mojave. I have also attached a
truncated version of the
ascii file for inspection purposes (the whole thing was too big), which was
converted from a csv
that was generated by a python script correcting for site effects. This script
took in as input the
original ascii converted from the original lh.thickness file using
mris_convert. The coordinates
correspond to the fsaverage template (~160k vertices in the whole file).
Thanks in advance for any guidance,
