External Email - Use Caution        

Hi,

We have a user trying to use fspalm.  I followed all the directions to install, 
but are getting an error with the new mri_surfcluster that we were asked to 
download with fspalm.  Here is the dummy command I ran to replicate the error:

mri_surfcluster --thmin 0 --subject fsaverage --hemi lh --in 
/usr/local/packages/freesurfer_v6.0.0/subjects/fsaverage/surf/lh.white

and the end of its output:

<...>
subjectsdir    = /usr/local/packages/freesurfer_v6.0.0/subjects
FixMNI = 1

mri_surfcluster: could not read surface 
/usr/local/packages/freesurfer_v6.0.0/subjects/fsaverage/surf/lh.white

It is the same error reported in these emails:

https://www.mail-archive.com/search?l=freesurfer%40nmr.mgh.harvard.edu&q=subject:%22%5C%5BFreesurfer%5C%5D+mri_surfcluster+ERROR%22&o=newest

but the error message is misleading.  The problem is not in reading the surface 
file, but in trying to read a file name made up of non-ascii (or presumably 
unicode) characters.  As shown by strace:

...
read(3, "", 8192)                       = 0
open("/proc/sys/crypto/fips_enabled", O_RDONLY) = 4
read(4, "0\n", 31)                      = 2
close(4)                                = 0
close(3)                                = 0
munmap(0x7f8413571000, 8192)            = 0
open("\310\215\26\f\376\177", O_RDONLY) = -1 ENOENT (No such file or directory)
write(2, "MRISread(\310\215\26\f\376\177): could not open"..., 
37MRISread(ȍ^V^L<FE>^?): c
ould not open file) = 37
...

Any thoughts on how to proceed?  Thanks,

-syam
