Absolutely. We're looking into adding a script with this functionality. Malte

External Email - Use Caution

Dear Malte, thanks for your reply. I need to apply a deformable transform. I've been using ANTs (antsRegistrationSyN and ApplyTransformsToPoints) and I would like to update that part of the pipeline with mri_synthmorph. Do you think it will be possible in the near future?

Best,

Ezequiel

________________________________________ Hi Ezequiel,

Yes, this is supported by mri_label2label if you save the coordinates in a .label file with vox2ras=3Dscanner in the header. These are simple text fil es; you can find examples in the label subfolder of a FreeSurfer-processed subject.

However, this currently only works for rigid or affine transforms, that is, LTA files. What kind of transform are you looking to apply?

Best wishes, Malte

Hi, I would like to know whether it is possible to apply a transform estima ted with mri_synthmorph to a set of coordinates (i have them in RAS space). These are SEEG electrode positions, and the transform maps between a subje ct's native space and the MNI152 template.

If this is not currently supported, is this something that might be added i= n the future?

Thanks a lot for your tools.

Best,

Ezequiel
