Hi,

Anyone seen this issue before?

Thanks,

Dont bother looking at this yet. I'll just update my repository and try again first (sorry should have done this before).

[twshimwell]

yeh still there in the latest master.

[epolisensky]

yep, I'm getting this error too. running 1.8.13

[gmloose]

Is this still an issue with latest PyBDSF (v1.10.2)?
