Thank you Mario.
Lots of helpful info in your first reply and I really do appreciate you taking the time to set out all these aspects.
I had worked out a couple of those problems already (e.g. the meterType = 5 and then the wavelength spacing was incorrect for a PR670) but by no means everything. It really was a rat’s nest of nested function calls originally!
The Nvidia card is a mess and I’ve already started taking steps to replace it.
We have a CRS Bits# that I considered using, but our experiment needs 2 subject monitors and 1 * Bits# cannot cope with that.
I’ll look on your GitHub master branch, for sure. I came into the lab today determined to write my own script, taking the best aspects of Brainard’s original functions, but it sounds as if that is no longer necessary with your new script.
The 11hrs is understood, and I know that “Thank you”s don’t pay the bills! I will try and get our budget controller to purchase some more support hours.
Best wishes,
Eric
