Hello freesurfer experts,

A volume file I want to save as a mask(the orange/red shaded areas in the picture) on top of my volume file does not align as seen in the picture. I have used mri_vol2vol to align the mask to my native volume but apparently it did not work out. I am trying to correct this by using mri_mask now;  I tried to use the option -xform %s which apparently applies the LTA transform to align mask to input volume, but now I get this error;

>>lab@lab-ThinkStation-E31:~/Desktop/freesurfer/subjects/sub-01_MW/mri$ mri_mask -xform %s MW_IIHC_aTAL.nii native.areas_MW_aTAL.nii MW_aTAl_masked.nii
transform file name is %s
WARNING: hdr.dim[4] = 0 (nframes), setting to 1
niiRead(): NIFTI_UNITS_UNKNOWN, assuming mm
DoAbs = 0
Apply the given LTA xfrom to the mask volume
Reading transform ...
ltaReadFile(%s): can't open file
No such file or directory
mri_mask.bin: could not read transform file %s
No such file or directory  


I would deeply appreciate if someone could help me sort out this mess.

Thank you all!
Best,
Idil
