I have read 118 files (from a directory) each with 2088 data and put them into a 2 D array with 2cols and 246384row, I want to have aeach file on a separate columns with 2088 rows

Question

I have read 118 files from a directory using the list.vi. Each file has 2 cols with 2088rows. Now I have the data in a 2 D array with 2cols and 246384rows (118files * 2088rows). However I want to put each file in the same array but each file in separate columns. then I would have 236 columns (2cols for each of the 118 files) by 2088 rows. thank you very much in advance.

Answer 1

Hiya,
here's a couple of .vi's that might help out. I've taken a minimum manipulation approach by using replace array subset, and I'm not bothering to strip out the 1D array before inserting it. Instead I flip the array of filenames, and from this fill in the end 2-D array from the right, overwriting the column that will eventually become the "X" data values (same for each file) and appear on the right.
The second .vi is a sub.vi I posted elsewhere on the discussion group to get the number of lines in a file. If you're sure that you know the number of data points is always going to be 2088, then replace this sub vi with a constant to speed up the program. (by about 2 seconds!)
I've also updated the .vi to work as a sub.vi if you wa
nt it to, complete with error handling.
Hope this helps.
