Hello.
I'm interested in using 3dmaskave to write out the global timecourse of ROIs over a certain threshold. In past postings (David Ludlow's question), it looks like it is possible to use 3dmaskave to input either an ROI mask or a threshold mask, but not both. Is there a way to do this? Can you have two masks in the same session? I have used 3dmaskave to output the voxel coordinates and intensity values in an ROI and then 3dmaskdump to get the timecourses of voxels above our threshold, but when an ROI contains many voxels, this is quite an arduous task.
Thanks for your help.
