Hi Tyler and others using the inter-hemispheric analysis. I have made some modifications to this method since I last released it in Aug. I found a slight bug in the process which I have fixed. I've also created cached tables for multiple comparisons correction. The instructions for installing are below. I doubt that the fix mentioned above will change your results much. However, if you want to use the tables, you will should to re-run everything.

Make sure to install ALL of the files below. DO NOT do a partial installation. Note that there is a new average subject. Make sure to delete the old one.

Hi,

I am comparing asymmetries in fmri activation, and have been following your instructions as per https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2011-August/019869.ht... , but when it comes to the multiple correction with mri_glmfit-sim I get an error that the --subject-override command was not found. The version currently installed on the machine is 1.36.2.1 from 2011/03/28 and I can't find a download for the newer version mentioned in the email above. Has one been uploaded?

Many thanks, Tyler Manning _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
