I uploaded a set of M67 images (BVIR) into VPHOT today and downloaded the text files to my PC. I then started TG, loaded the text files and clicked the Calculate Transform Set button - it displayed the error message above and went no further. Ideas? ...Lane

What comps did you use?

standard field

However, this is the first time I've used Vphot - I followed the user guide instructions, when it displayed my M67 image(s) it identified many stars in the image so I think I got it right...Lane
