in thread Running rpsblast on all files in directory, using perl

That's what happens when you copy from some auto-correcting MS app like Outlook, it changes a plain dash into an 'en dash'. E.g., according to the Unicode Sliderule, '–d PF' is:
Char 08211 | U+2013 | en dash Char 00100 | U+64 | small d Char 00032 | U+20 | space Char 00080 | U+50 | capital p Char 00070 | U+46 | capital f
