I tried installing undr so I could download and mess around with reading in AEDAT spike train data.
I get an SSL verify failure. Do you think I can just turn SSL verification off momentarily in code?
Is the problem partially one of credentials? Like the databases I am trying to read from may not be public, and its assumed I am signed in through the shell?

UNDR is a work-in-progress and I'm working on major changes that may fix this problem. Nevertheless thank you for the report, I'll keep an eye on this issue.
