Hi FS experts and users

I created a rIPL mask by other tools and I want to make it surface-based mask. I ran this command:

mri_vol2surf --hemi rh --reg register.dat --mov ./rIPL.nii.gz --o ./rIPL_afni.mgh --trgsubject fsaverage

And it echo this output, that is to say, it cannot find the register.dat. I want to know where the file is :

=============================

srcvol = ./rIPL.nii.gz
srcreg = register.dat
srcregold = 0
srcwarp unspecified
surf = white
hemi = rh
trgsubject = fsaverage
surfreg = sphere.reg
reshape = 0
interp = nearest
float2int = round
GetProjMax = 0
INFO: float2int code = 0
Done loading volume
regio_read_register(): No such file or directory
Could not open register.dat

====================

Thanks

All the best
