Why does strtok cut too much out of my string?

Hi,

I am using the strtok function to cut out a certain part of my strings. I have a lot of filenames with the exact string in the beginning of the name and would like to get out the last part of the string.

Eg: Filenmes{1,1} = 'ID_setup_CMJ_L_2' Filenmes{2,1} = 'ID_setup_DJ_R_1'

So I want to get something like:

Names{1,1} = 'CMJ_L_2' Names{2,1} = 'DJ_R_1'

I use the following line for this:

   [prt1, prt2] = strtok(filenmes{i,1},'ID_setup_')

It works fine for all of my filenames except for the DJ's.. then it gives me Names({2,1} = 'J_R_1' (instead of DJ_R_1).

Thus, it cuts out that 'D' which it does not do in all of my other examples (CMJ,NonCMJ,HH,...)

Any suggestions? Are there perhaps better ways to do this?

Thanks!

This is because you specify a set of delimiters in the second argument of the strtok function, and 'D' is a delimiter. Leading delimiters are ignored, so the D in JD is cut.

Instead of strtok, you can may want to use strrep

newfilename = strrep(filenmes{i,1},'ID_setup_', '');

Great! Works perfectly. Thank you!
