Chromosome And Scaffold Naming Convention

Question

[Boboppie]

I see chromosome/scaffold name/id can contain character, digit, underscore(_), dot(.), slash(/), etc.

Does a convention exist?

[Larry_Parnell]

For human or other scaffolds?

[Sean Davis]

The general answer would be "no", I think.

[Haibao Tang]

dot and slash are rather uncommon in the names though

[Boboppie]

@Larry_Parnell I mean in general.
