How to continue from a previous alignment

This guide shows you how to start from an alignment that was uploaded earlier, to refine it or to compare it with another.

Steps

  1. Open the session. Each shank starts from its most recent uploaded alignment, or from a recovered alignment if one was saved with Save Progress (see How to save work in progress and recover it).

  2. To start from a different one, choose it from the alignment dropdown in the top right corner. The alignments are listed newest first, by the date and time they were made (and the user, when one is known), with original (no alignment) last. The reference lines of the chosen alignment are drawn and the fit is applied straight away.

    The alignment dropdown open, listing two new alignments, the 2021 alignment and original

  3. Move, add or remove reference lines and apply the fit as usual.

  4. Upload. The new alignment is added to prev_alignments.json; the earlier ones are kept.

With more than one shank, the dropdown applies to the active shank. Switch shanks first.
