Edits

This page lists all the various possible edits that could be made to subject data supported by the recon-all stream (both the default 'cross-sectional' stream, and the longitudinal stream). 'Edits' is the term that describes manual interventions by a user necessary when the automated stream (recon-all) does not produce output that is correct or suitable as determined by the user, or if the automated stream fails outright. Manual interventions occur via the volume editing tool tkmedit, or tkregister2 (which 'edits' the alignment to Talairach space). Note that 'edits' are made only to volumes. There is no such thing as a surface edit. Problems with the surface are corrected by making edits to an appropriate volume. See troubleshooting.

Edits are treated as permanent changes, in the sense that once an edit is made, it is saved to a file (either a voxel change in a volume, or a text file listing points), and it is automatically re-used by recon-all when recon-all is run. This is in contrast to the host of possible recon-all flags that could be added to alter the operation of an executable but are not saved to disk (and not re-used by recon-all, thus necessitating the user to specifying them again on the recon-all command string if that operation is desired). Specifying an alternative watershed threshold for the skullstrip operation is an example of a 'non-persistent' edit (one which is not saved to disk).

All of the edits made to a subject can be revealed by using the -show-edits option of recon-all (available in v5.X):
