Your description is very vague.

Please add a few lines to your sample input for a subject with a 2-digit subject number, and then show us the exact names of the output files you want to have produced from that input and the contents that should be saved in each of those files.

You show the name of the output files as s00x_run1_condition1_ACC1. Does that mean that subject 25 should have filename s00x_run1_condition1_ACC1, s0025_run1_condition1_ACC1, or s025_run1_condition1_ACC1?

What field delimiter do you want between output fields? Your input has tabs as separators for most fields; but some use a space and a tab; and some use a space, a tab, and several more spaces?

Do you want to throw away the data in the 1st four fields in the new, split files; or do you want to preserve the current lines but just split them into new files?

X2SYS_MERGE(1gmt)					       Generic Mapping Tools						 X2SYS_MERGE(1gmt)

NAME

       x2sys_merge - Merge an updated COEs tables

SYNOPSIS

       x2sys_merge -Amain_COElist.d -Mnew_COElist.d

DESCRIPTION

       x2sys_merge  will read two crossovers data base and output the contents of the main one updated with the COEs in the second one. The second
       file should only contain updated COEs relatively to the first one.  That is, it MUST NOT contain any new  two  tracks  intersections  (This
       point  is  NOT checked in the code). This program is useful when, for any good reason like file editing NAV correction or whatever, one had
       to recompute only the COEs between the edited files and the rest of the database.

       -A     Specify the file main_COElist.d with the main crossover error data base.

       -M     Specify the file new_COElist.d with the newly computed crossover error data base.

OPTIONS

       No space between the option flag and the associated arguments.

       EXAMPLES
	      To update the main COE_data.txt with the new COEs estimations saved in the smaller COE_fresh.txt, try

	      x2sys_merge -ACOE_data.txt -MCOE_fresh.txt > COE_updated.txt
