Good morning everyone, if I am writing something in a wrong way please let me know. However I am using the afore mentioned method in python to get pairwise CA-CA distances of two sets of residues in a pdb file, sometimes there are two CA due to incertainties and this will change the output from:
[[X]]
to:
[[X X]]
where X are floats, sometimes the output is [[]] and some other times is [], how can manage all these exceptions in a smart way? tried to convert those to string and .strip something here and there, didn't really work, at the moment the error I get is the following:
if distmap[0][0]:
IndexError: index 0 is out of bounds for axis 0 with size 0
Which should be due to the [] case, I need to append these values to a list in a str(round(float(X),2)) format. The blank cases I would prefer to not be reported as 0 but for istance an insanely huge number such as 100, or not reported at all.
Please let me know if you need more info and if I need to change the form of my question
Can you try the following:
if distmap.size == 0:
# Do something when distmap is empty
You can also use distmap.shape to identify its dimension.
