It looks like mris_transform interface changed since Freesurfer 5.3. In Freesurfer 7.4.1, I believe you need to specify both --trx-src <> and --trx-dst <> if you are giving mris_transform the transform in xfm format. Or, you can use lta_convert to convert xfm to lta.
Best, Yujing From: [email protected] <[email protected]> On Behalf Of Noemí Hostalet Sent: Tuesday, April 16, 2024 7:13 AM To: [email protected] Subject: [Freesurfer] Error using mris_transform in Freesurfer 7.4.1 External Email - Use Caution Hi, I'm trying to run the following mris_transform command in Freesurfer version 7.4.1: mris_transform group1/z/Freesurfer/surf/lh.smoothwm group1/z/Freesurfer/mri/transforms/talairach.xfm group1/z/Freesurfer/surf/tal/lh.smoothwm.tal.asc But it's giving the following error: The transform does not have the valid src volume info. Either you specify it with --trx-src or make the transform to have the valid src info. In a previous version (Freesurfer 5.3) it ran without problems. Do you know what could be the problem? Thank you -- Noemí
