Seq view label spacing
This controls how the sequence indices are shown in the sequence viewer. Setting this to 1 means every index will be shown, setting this to 5, means that every 5th residue index will be shown in the sequence viewer.
Note: Don't forget to turn on the sequence viewer, set seq_view.
# set to any positive integer set seq_view_label_spacing, int # for example, set it to 5 set seq_view_label_spacing, 5
