Hi Antonin and Tim
you should be able to do: setenv FS_SKIP_TAGS 1 mri_convert vol_with_tags.mgz vol_without_tags.mgz
and verify it worked with mri_info

Hi, Tim, the subject ID can be also contained in the commandline history which is sto red in .mgz files. This can be viewed using mri_info file.mgz --cmds I am not aware of any direct command which can strip out this info, but you surely could convert .mgz file to .nii and then (using path which does not c ontain subject ID) convert back to .mgz, if needed. Antonin Hi Doug,
thanks for the mri_add_xform_to_header idea, I didn't know about that option !
Best,
Tim

For the mgz volumes, you should be able to do something like mri_add_xform_to_header -c /new/path/to/xfm brain.mgz
For the labels you could just use something like sed s/oldsubjectname/newsubjectname

External Email - Use CautionHi Douglas,
sure, you can get two example files here:
wget http://rcmd.org/tmp/brain.mgz wget http://rcmd.org/tmp/lh.BA1_exvivo.labelThe brain volume contains the ID because it stores the full path to the tairach xfm (which includes the folder name, so the ID). You can check b
y:
mri_info brain.mgz | grep talair(In this case the ID is 'tim').
Without mri_info, you can get it as well:
mv brain.mgz brain.gz gunzip -c brain.gz | strings | grep talairThe second file is an ASCII label from the same subject. You can get the
ID
by running:
head -n 1 lh.BA1_exvivo.labelThere are some other files which contain the ID, these are just 2 exampl
es.
I am currently in contact with the people running the consortium server
and
I am not really sure whether the rule that the ID must not be in the fil
es
makes any sense at all. Maybe I can get around this.
Best,
Tim

Hi Tim, can you send a list of files that have the identifier. For volumes and surfaces, it might be as easy as running mri_convert/mris_convert using the same file as input and output.

External Email - Use CautionDear FreeSurfer experts,
I have two questions on subject IDs in FreeSurfer output.
- is it possible to change to subject identifier in the FreeSurfer
output after recon-all has been run?
Background: I would like to upload data pre-processed with FreeSurfer
to
a consortium server. The subject ID is a random identifier, but the upload guidelines say this identifier must only occur in certain file types (Excel files, .log files, and some more, but not in any other files).
I noticed that a lot of the output files produced by FreeSurfer contai
n
the subject identifier somewhere, including various binary files, so I
guess there is no easy way to change it. But maybe there is? Like rerunning a part of recon-all?
- If not, I could rename the source NIFTI files (e.g., from the
identifiers to something like 'subject001', 'subject002', ...) and re-process everything. This would take some computational time for the
500 subjects, but it would be okay I guess.
But a large number of the subjects have manual edits applied already.
Is
there a way to keep the manual edits? E.g., I thought maybe I could rename the individual directories of the edited subjects, leave the edited files in there, and run recon-all again. But what would happen?
Will the new output files have the renamed ID from the directory name (and thus the recon-all command line), or will they still use the old
ID
(from the header of the existing files)? Or will the existing, edited files which contain a different ID be ignored during the new run becau
se
the IDs do not match, and thus the existing edits would have no effect
?
All the best,
Tim
