did you check the output? I think it should have the appropriate number of
frames. You can use mri_info to check the dimensions

Hi There,
I’m currently trying to run mri_vol2surf on some animal data and surfaces I’ve
been working with.
I’m having a bit of a problem with the command mri_vol2surf.
I seem to be able to project my functional volume to my surface, however I’m
currently only projecting the first volume of my functional time series onto
the surface.
I realize the default option for frame is the first volume if output is set to
a paint file, however I’m not trying to do that.
Ideally I’d like to project all the volumes for later connectivity analysis.
The command and terminal output are as follows:
mri_vol2surf --mov rest.acp/filtered_func_data_clean.nii.gz --reg
rest.acp/reg/example_func2FS.dat --surf white --projfrac 0.5 --hemi lh --o
rest.acp/test.func.mgh
srcvol = rest.acp/filtered_func_data_clean.nii.gz
srcreg = rest.acp/reg/example_func2FS.dat
srcregold = 0
srcwarp unspecified
surf = white
hemi = lh
ProjFrac = 0.5
thickness = thickness
reshape = 0
interp = nearest
float2int = round
GetProjMax = 0
INFO: float2int code = 0

The actual functional volumes has 300 volumes, so I feel like I should be
getting Dim: 19181 1 1 300 ?
any advice?
thanks,
