Dear Experts,

I'm trying to extract number of voxels from my TBSS corrected t-tstats image. I would like to use a ROI mask and know the number of significant voxels inside the area. I tried this command:

"fslmaths mask -mul tfce_corrp_tstat2.nii.gz -thr 0.95 output" to mask my t-stats image, and I'm not sure about the output image. The output image seems to only include significant voxels inside the region, but the intensity value is somewhat weird. I suspsect that it might be the actual t-value?

I plan to then use the cluster command to generate the information of the number of voxels....but I am not sure if this way is correct.

Any suggestions?

Thanks in advance,

Catherine
