Dera Mathgroup, I have a bunch of files with name pattern, abX_pattern1_pattern2.txt. I would like to Import many of these files, operate on them and then save the output to another file. 1. How do I go about writing something in Mathematica which will import the files by recognising the patterns. In the above pattern1 is an integer and pattern2 contains a numbers and the letter o (e.g pattern2 = 0o5 or 0o1) automatically. An example from my notebook is as follows, w8 = Import["ttX_1000_0o5.txt", "Table"]; 2. After this I operate on the data which produces an output of two numbers l, and m. I want to write these output values to a file as columns of l, m, pattern1, pattern2, with pattern 2 converted to a number ( in the example above, 0o5 to 0.5 say), then move on to the next file and so forth. Any help will be appreciated. Thanks Yas
