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 Rujing Zha 2014-04-26
