Sorting tiers with concatenate

[rbennett24]

When concatenating TextGrids it appears that tiers are re-sorted in alphabetical order. Is there any way to disable this?

That could be done of course but the reason we sort tiers by their names is that tiers in the concatenated TextGrids do not necessarily need to come in the same order. One thing that could be done is to only sort when there is a mismatch.

More generally, however, while using TextGridTools one should not depend on the order of tiers too much. One does this while writing Praat scripts because Praat’s scripting language lacks a good way of accessing tiers by name. By contrast, tgt.TextGrid objects have a get_tier_by_name method, which should be always preferred over relying on tier indices.
