All models currently in the default:

• "AIGKC_202401",
  -"BBRKC_202401",
  -"NSRKC_202401",
  -"SMBKC_202401",
  -"SnowCrab_202401",

Get errors like gmacs.par_old does not exist for 'NSRKC_202401'. Can't do test. and Error in "if (nrow(pars_new) != nrow(pars_old)) { :" argument is of length zero.
