Dear all,

I want to move from matlab for my image processing tasks. Nevertheless, to load the file formats I use (SPIDER, MRC, etc..), I only have some python code. Is it possible to directly invoke such python code from SAGE?. If so.. how? (I have looked for a Python inteface, but no luck for SAGE invoking Python). If not.. what is the recommended workflow to program and publish my codes for the community?.

Thanks in advance!

Short answer is yes. Are you looking for this in the notebook or command line?

Here are at least 3 ways:

Run the code with sage -python filename.py
In the notebook, choose "python" in the dropdown list at the top.
In the notebook, put the code in a cell with a %python at the top of the cell.

What about some pure python in the interpreter? i'm using sage interpreter in emacs...

The main difference is the preparser. You can turn off the preparser with `preparser(False)`. But I should also say---have you tried just running your code? Most python code runs just fine directly in Sage, even with the preparser on.
