Support slicing shorthands #25

Closed karlcz closed 7 years ago

karlcz commented 7 years ago

For the ZYX Slice parameter, support shorthand notations where the upper or lower bounds of the slice can be omitted:

A:B the normal slice in half-open interval [A,B)
A: the slice [A,L) where the axis has L grid steps
:B the slice [0,B)
: the slice [0,L) where the axis has L grid steps

I committed this change. It was actually in volspy/util. I tried to look for other occurrences of the environment variable name and don't think we need to patch anything else as they don't re-parse it.

I tested that this round-trips through automates server-side processing into the block analysis code in batch mode.
