[Sidefx-houdini-list] COPs sequencing, interleaved rather than end-to-end?

Assuming that your images are in "C:/Images/", that your frame count starts
at 1, and your files are numbered also starting at 1, then this expression
should do it:
But you have to make sure that you enable "Override Frame Range" on your
file COP and set "File Range Length" to something sensible. Otherwise it'll
try to auto detect, apparently without much success.

Subject: [Sidefx-houdini-list] COPs sequencing,interleaved rather than
I have an ordered sequence of images on disk with the following naming
What clever expression in a File COP would load these files in order?
At the moment I have 3 File COPs, one each for the 'a', 'b' and 'c'
sequences. Merged together, I was then looking at the Shuffle COP for
in-place (non-cached) reordering.
Of course I could just rename these files with a bit of python
(untested) and be done with it ... but I'd prefer a houdini solution.
from glob import glob
files = glob("img*.png")
for i,f in enumerate(files):
os.system("mv %s newimage%4d.png" % (f,i))
