External Email - Use Caution
Thank you. I guess I am still confused on how to actually get results to visualize. I would like to assess left-right hemispheric cortical asymmetry . Ideally, i would like the analysis to be paired (ie. L vs R for each subject, rather than the average of L vs average of R across subjects). How would I go about analyzing and visualizing this in freesurfer using xhemi. Also is there a way to this with a ROI rather than the whole brain?
Thanks,
Carlos

I am trying to do an asymmetry analysis using steps detailed in *MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be* https://secure-web.cisco.com/1_yNnJ9fMi64wWs9Ha4WPhzOEIiP_nSgP3fNcqEdlPAUTHB... https://secure-web.cisco.com/1E9BKFPFixB_mpRwvgfFNlEN0qYfJdo8MVLo6aeqDf-afyiae0jseDSkmT4rjZVPVW2YddkoaVShtXUvmMsZD2Q-O-EMrqoRl9tSf1WZdkCT-CHkbB5CF1uzhSSh52snNjiVSUe06Hglkpgu0zWkav2vu-QdQ9SI82oqSGVYhDWH2OrUtc9r-If8eYFj3engrDG1rTdNx-nUlQfLR4sDnC7xSGjz5joW_VQ91mx5zoRqiJRipABc1J_XyomlcuybTD_qYerY4spWepy4DYT69qhv4ush_fMBBytkxd2h1sE4pHwpxMg_BUR5CoVcqKGPclpe-J-6ZS5kwFL7RnVDnXg/https%3A%2F%2Fsurfer.nmr.mgh.harvard.edu%2Ffswiki%2FXhemi
However, step 1.3 starts with running:
mris_apply_reg --src lh.map.mgh --trg lh.map.lh.fsaverage_sym.mgh --streg $SUBJECTS_DIR/subject/surf/lh.fsaverage_sym.sphere.reg $FREESURFER_HOME/subjects/fsaverage_sym/surf/lh.sphere.reg
What is this lh.map.mgh file? and where can I find it/how can i make it?
Thank you,
Carlos
