Ticks in the linear viewer are 1 base off

[cmonnom]

Describe the bug

Ticks under the sequence in the linear viewer are placed under the wrong base.

For example, the tick labeled "1" is under the 1st base which is at index 0.

Expected behavior

Since everything is 0-based, the tick should either start at 0, or (better?) placed between the 1st and 2nd amino acid.

Maybe something like this:

Rather than the current:

Hey @cmonnom, as you've flagged the UI is 1-based while the input/output are 0-based. I'm not sure we can change that now, though, without breaking folks' existing workflows (which would be worse than fixing it). Further, IIRC most tools biologists use are 1-based so that's what the viewers attempt to show: 1-based indexes

Would it help if the demo were fixed? I agree that header being 0-based is strange given all the rest of it.

Hi @jjti , I think I understand what you mean: SeqViz internals use a 0-based system but what's shown to the user is a 1-based index. (what users of the library have access to are the 0-based start/end).
