Re: [Freesurfer] Downsampling from fsaverage to fsaverage6

Hi Matthieu

sorry, I don't understand. All the files are binary, no? Are you getting 
an error?

Dear FS's experts,


I am trying to downsample some surface data from fsaverage to fsaverage6 with 
the following command:


 mri_surf2surf --hemi lh --srcsubject fsaverage --sval 
./lh.fsaverage.s8mm.mgh  --trgsubject fsaverage6 --tval 
./lh.fsaverage6.s8mm.mgh --cortex


However, the output surface data is a binary file contrary to the source one 
(please see attached).


Would anyone have an idea of the problem?

Best,

Matthieu

Hi Bruce,

The input file has not only binary values (0 or 1) it is made of float 
values, whereas the output mri_surf2surf contains only binary values.


Best,

oh I see. I thought you meant the file format was not binary. Hmmm, not 
sure. Maybe Doug will have some insight, as I didn't think surf2surf would 
binarize by default

Hi Doug,

In which version of FreeSurfer does this bug appear? And under what
situation does this bug appear?

I swear I have used the command with similar flags, but did not experience
this bug.

Thanks,
Thomas
