Hi all,
Within QDEC, when I click on the "Find Clusters and Goto Max" button I can see the individual thickness values per datapoint.
- I am co-vaying for age: would these values be raw thickness values
or estimated margin means?
Raw thickness
- Considering I have 100s of subjects and several ROIs, how do I
export these values for all subjects? I can click on each data point and copy the terminal readout or create an ROI, map label to subjects and export it out but both approaches are time consuming and prone to human error. Is there a way of using existing QDEC setup files to export all this data out more cleanly?
QDEC will create a file call y.mgh in its output directory. This will have a frame for each input subject. You can extract a single vertex or an average over an ROI using mri_segstats, specifying y.mgh as input and your label as part of the --slabel option. Or spec --vox C 0 0 where C is the vertex you want to extract doug
