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 Done loading volume INFO: This REGISTER_DAT transform is valid only for volumes between COR types with c_(r,a,s) = 0. Input reg is register.dat -------- original matrix ----------- 0.99985 -0.01410 0.01053 2.56773; 0.01269 0.99230 0.12321 -20.18632; -0.01219 -0.12306 0.99232 0.65897; 0.00000 0.00000 0.00000 1.00000; -------- original matrix ----------- Reading surface /Volumes/brain/PCP_func/5489/anat/surf/lh.white Done reading source surface Reading thickness /Volumes/brain/PCP_func/5489/anat/surf/lh.thickness Done Mapping Source Volume onto Source Subject Surface 1 0.5 0.5 0.5 using old Done mapping volume to surface Number of source voxels hit = 2868 Writing to rest.acp/test.func.nii Dim: 19181 1 1
The actual functional volumes has 300 volumes, so I feel like I should be getting Dim: 19181 1 1 300 ?
any advice?
thanks,
austin
