I am using TG for V and B files (one each) processed in VPHOT. After entering the required info into TG and selecting the V and B photometry report text files which were saved to my computer I clicked on Calculate Transform Set which resulted in the following error message: "Need at least two filters data to create transforms". What are some possible causes and solutions?
