How to split this txt file into small files?

Dear shell experts,

I would like to spilt a txt file into small ones. However, I did not know how to program use shell. If someone could help, it is greatly appreciated!

Specifically, I supposed there is file named A.txt. The content of the file likes this:

Code:

Subject	run	condtion	ACC	time 	duration	weight
2	1	1	0	122.6 	2	1
2	1	1	0	144.8 	2	1
2	1	1	1	132.6 	2	1
2	1	1	1	182.6 	2	1
2	1	1	1	198.6 	2	1
2	1	1	1	230.6 	2	1
2	1	1	1	308.6 	2	1
2	1	1	1	368.6 	2	1
2	1	1	1	382.6 	2	1
2	1	1	1	410.6 	2	1
2	1	2	0	294.8 	2	1
2	1	2	0	394.8 	2	1
2	1	2	1	66.6 	        2	1
2	1	2	1	78.6 	        2	1
2	1	2	1	158.6 	2	1
2	1	2	1	207.1 	2	1

..........................
I want to split the last three columns into many small ones. if the fourth column, namely "ACC' is zero, I want to put them into a txt file, named "s00x_run1_condition1_ACC0". If the fourth column, namely "ACC' is one, I want to put them into a txt file, named "s00x_run1_condition1_ACC1"

For example, in the first two rows, the ACC column is zero, so I put the first and the second column into one txt file, and named "s00x_run1_condition1_ACC1", there are 50 subjects and every subject have 6 runs, and every runs have 3 conditions.

Although I can do those manually, it is a time-consuming task. Thus, if anybody could help, it will be greatly appreciated!

Thank you very much in advance!
