Use mri_vol2vol --reg register.dof6.lta --mov fmcpr.nii.gz --fstarg --o fmpr.conformed.mgz Then use the conformed thalamic nuclei volume when running mri_segstats

Thanks!!
Using mri_segstats, is the input subj/rest/001/fmcpr.sm6.mni305.2mm.nii.gz? Or should I use the .odd like fmcpr.odd.sm6.mni305.1mm.nii.gz or fmcpr.odd.sm6.mni305.2mm.nii.gz?

You'll need to either convert the time series data into the conformed space or the segmentation into the functional space. The first is probably better (it will create a huge file but you can delete it when you are done). Use mri_vol2vol --reg register.dof6.lta --mov fmcpr.nii.gz --fstarg --o fmpr.conformed.mgz Then use the conformed thalamic nuclei volume when running mri_segstats

Hi list, I would like to extract fMRI time series from the thalamic subregions that I obtained by the recent tool implemented in FS.
I have run mri_segstats --seg subj/mri/ThalamicNuclei.v10.T1.mgz --ctab $FREESURFER_HOME/FreeSurferColorLUT.txt --i subj/rest/001/fmcpr.sm6.mni305.2mm.nii.gz --avgwf Time_Seriesfolder/ADNI011_HC.MNI --id 8120 --id 8121 --id 8122 --id 8123 --id 8220 --id 8221 --id 8222 --id 8223
The command produces this error: ERROR: dimension mismatch between input volume and seg input 76 76 93 seg 169 105 118
Please, I have other questions for you.
1) At starting, I have used the command line reported below:
preproc-sess -sf sessid -fwhm 6 -surface fsaverage lhrh -mni305 -fsd rest -per-run -sliceorder odd
The -mni305-1mm could be more useful? My raw-data are: data_type UINT16 dim1 64 dim2 64 dim3 48 dim4 140 datatype 512 pixdim1 3.312500 pixdim2 3.312500 pixdim3 3.312500 pixdim4 3.000000 cal_max 0.0000 cal_min 0.0000 file_type NIFTI-1+
2) In the mri_segstats the input is subj/rest/001/fmcpr.sm6.mni305.2mm.nii.gz. Do you agree? Conversely, should I use the .odd like fmcpr.odd.sm6.mni305.1mm.nii.gz or fmcpr.odd.sm6.mni305.2mm.nii.gz?
3) If I interested to obtained the time course from a unique region expressing the merging of some thalamic regions (i.e. 8121plus 8122 plus 8123), which is the options that should I added?
Thanks,
Stefano
