Some transforms from native surface to the dHCP Symmetric 40week surface template are not valid gifti files (structural pipeline)

Hi,

some transforms from native surface to the dHCP Symmetric 40week surface template are not valid gifti files. I looked into the files and the point set data arrays are correct, but they are invalid as the closing tags are missing. Also, the triangle data arrays are partly or completely missing. Examples:

  • sub-CC00149XX18_ses-49000 right
  • sub-CC00366XX12_ses-116300 left
  • sub-CC00516XX13_ses-152902 right
  • sub-CC00713XX12_ses-229000 right

You can see (even in the torrent) that these transform files are about half in size compared to the proper transform files.

Edit: these files are named as xfm/sub-{subid}_ses-{sesid}_hemi-{hemi}_from-native_to-dhcpSym40_dens-32k_mode-sphere.surf.gii

Hi @NeuroStar,

Organising the torrent was quite challenging, and the dHCP team are working towards uploading the neonatal data to NIMH. In the meantime, can you send me an email so I can pass these onto you?

Best wishes,

Logan
