Amy, VLBAFIX will not work unless the the FQ numbers are all present in the FQ table 1 - NROW. It is easy for there to be 2 rows and 2 FQ numbers (but value 1 and 3 say) since FITLD does not write FQ rows for FQs with no data. I am now fixing FITLD to concatenate properly after such a file. Best fix - read the FQ number in row i in the loop over FQ rows. Eric
