Re: [HCP-Users] group-ICA spatial maps

Thank you very much Steve for your prompt response! 1. I looked into Beckman IEEE TMI 2004. Is there any way to find out the threshold 'Z-stats' for each IC corresponding to the 0.5 posterior probability activation in the framework of Gaussian mixture model? In other words, how to use the

Re: [HCP-Users] mapping correlations on a template

If your .csv file matches a particular .dlabel.nii file, what you could do is use -cifti-parcellate to generate a template parcellated cifti file, and then use -cifti-convert -from-text to put the data into that format (you will need to strip off the labels first, leaving only the numbers, after

[HCP-Users] mapping correlations on a template

Thank you for any insight or advice - This is my first use of freesurfer (and MRI methods in general) so I apologize if the question is overly simple. I have generated an analysis of HCP MEG data and have found correlations of MEG metrics with Freesurfer volume and thickness measurements you made
