External Email - Use Caution Hi Yujing
I figured it out – it turns out the R package shifts vertex indices by 1 by default, I was able to fix the problem by changing the option to stop the index adjustment because I was merging information from two recon-all outputs so the vertices matched and did not need adjustment. It all works well now !

What is your R command to generate the label file, and how did you view it in freeview? Here is some information about the label file - https://secure-web.cisco.com/1kVu6_IiZScP9EYNWQitJjEIFJdUx0QuQH7iOdSfCbdff1Zra9hliBt7NbQ07ufIf7XpI7Q7cg2TsyhhRg99JXB_bvuwUdIEubOacX_FLRFSLSHwP2NWeIASiQjQhr7sFLQCmk8txNrpy-XeaD8zS3XMf51QtgK86gMilf_ButyeUqI2UGjXTzIXil7q4PsuFUspq-GqpajBqvV1AW99Kd3K10557eRkKrl0ddHneh-O8iNy60rKq5CQs-IYm-faxymj3eODPfA_bYwy0XSKw74mBkbPFWIWmWGLghFMcqr4a4fECcmcb9IHdDdC4xNbJlznMe4dOpxXRhSlywDTg5g/https%3A%2F%2Fsurfer.nmr.mgh.harvard.edu%2Ffswiki%2FLabelsClutsAnnotationFiles<https://secure-web.cisco.com/1uDxySNuq_9_-MMs2CT-ED6FQkzIZHrooSJMYE-RxgRGs4CUR00R3_p5_6cbvWEpf4pD2W4bNdrqjkCT98sMrFzgg-qLlsjpm1lhJOKH0QbzbGk5vE1XTTQGJC6gAFDNmXdnETB8Asmm2HQmS0ZsRfprP3ybcfa7YNFlTDaEmBZPgqxfEjThlLBgl6puAX3rjBYKj-jy8HbxHBS2JvWyrsOXHTDkdzkDnPAz9Y-vPC36B3e5FIoD-txmQy9BFR_8L-XuQGAMBHp3vn91bsMdNEDT86UOwV5AfW3LNLUXvADjARwdjMo1x7xKog-kFLpmblNHPqLsIRMBDylNPtL3_Tw/https%3A%2F%2Fcan01.safelinks.protection.outlook.com%2F%3Furl%3Dhttps%253A%252F%252Fsurfer.nmr.mgh.harvard.edu%252Ffswiki%252FLabelsClutsAnnotationFiles%26data%3D05%257C01%257Cyigu.zhou%2540mail.mcgill.ca%257C4572f09d23404026ef8e08db1feaf04a%257Ccd31967152e74a68afa9fcf8f89f09ea%257C0%257C0%257C638138866135664219%257CUnknown%257CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%253D%257C3000%257C%257C%257C%26sdata%3DhQZEGqub%252BpgWxF29I%252Fy6S%252BGQlbxQA%252BZPpnw0QNAwaXs%253D%26reserved%3D0> Besides the first two lines in the file, it needs 5 columns on each row. The error message suggested your label file doesn’t follow the format on that line. Best, Yujing From: [email protected] <[email protected]> On Behalf Of Yigu Zhou Sent: Tuesday, March 7, 2023 1:22 PM To: [email protected] Subject: [Freesurfer] freesurfer could not parse freeview-loadable surface label External Email - Use Caution Hello Freesurfer community I am trying to transform a label file obtained in subject native surface space to subject native volume space. This label file was obtained through binarizing the subject lh.sulc morphological data through the function write.fs.label from R package freesurferformats, in the left hemisphere, resulting in a binary label for all sulci in the subject. Visual quality control of the label file through Freeview was adequate: I can load the surface label file with any surface of the subject. Now, I would like to map the corresponding voxels that belong to sulci in the left hemisphere of this subject. I tried to convert the label to volume using mri_label2vol first, but got the following error message could not parse 48510th line '1e+05 -37.5524826049805 -5.55967617034912 18.56817436218261' in label file I then tried to first convert the file to annot format using mris_label2annot and then convert to volume using mri_aseg2aparc. Similarly, mris_label2annot threw the error could not parse 48510th line '1e+05 -37.5524826049805 -5.55967617034912 18.56817436218261' in label file The list described similar errors but no obvious solution that I can access right now e.g. having a developer inspect the label file. I would love to get any pointer as to why the label file may have been unparse-able to Freesurfer tools. Sincerely Yigu
