Segmentation and spatial normalization sometimes require a manual registration of the T1 to the MNI space. Normalization and segmentation usually fail completely, and so problems are easy to see with a "checkreg" between normalized files and a template.

- T1_initnative_[N]series
- Single T1 in original native space; if more than one series was collected, this file is the average of all series.
- T1_manual2MNI
- A single T1 that can (optionally) be manually registered to the template. This initially is simply a copy of the native T1 (previous step).
- T1_ref_vox...bb...
- A resliced version of the T1; this becomes the reference for native space.

1 | subject folder in T1preprocess |
2 | individual series with nifti files (copied from rawimages) |
3 | average of T1 series; defines native space |
4 | copy of native space T1, which can optionally be manually registered |
5 | resliced versions of T1; two different reslice options are used (on with 0.7mm voxels the other with 0.9mm) |
