I often use hyphens in filenames to separate information logically. But when I try to use these filenames in scripts using the pm command, I get the error “Error in pixel math ‘mtf(0.01, r_IC_1805-ho_00001)’ at symbol 18”. As I understand it, Cyril considers the hyphen in the file name to be a minus. Is this a bug or a feature? Maybe it’s better not to interpret the hyphen between $$ as a minus?
Hello, that would be a parse error indeed, thanks for the report!
