check this: Need to update PICTLISTR.TXT input file. Need to specify required files/directories to run. needs SUMFILES, NOMINALS, make_sumfiles.txt, etc
Description
- check following wording to be parallel with another entry.
This program takes position and SPICE file information from SPC and outputs it in files for export to other users. So far, the other user has mainly been KinetX; they use SPC info in their navigation software.
regres requires the directory "REGRES_FILES" in the working directory. regres exports files for each picture (<PICTURE NAME>.TXT) to the "REGRES_FILES" directory.
regres uses all pictures in PICTLIST.TXT and landmarks in LMRKLISTR.TXT to make the exported regres files. However, if you have created a PICTLISTR.TXT, regres will only use the pictures from that file.
