[off topic]
Yes, I know python’s a sticking point for sure, and I totally understand having been there myself! I think the idea with cs-tools is to let “power users” work with features the minute they think of them, but unfortunately the Venn diagram of advanced cryoEM practitioners and python programmers is not a circle!
On my list is a guide page along the lines of “Python for cryoEM”. If you have collected specific sticking points from trainees (i.e., beyond “the command line is frightening”, which I don’t in any way mean to downplay) I’d be very interested in hearing about them (although perhaps in their own forum topic 
)!
