I have imported a bench of text file into MATLAB using

list_files2load = dir(fullfile(directory1,'Mod1*));

But then in those files (here is an example: Mod1-A-00k.txt, Mod1-A-10k.txt, Mod1-A-30k.txt; Mod1-B-00k.txt, Mod1-B-10k.txt, Mod1-B-30k.txt), I would like to pick only the ones that end with '*00k.txt'

how could I do that?

Thanks

a={'Mod1-A-00k.txt', 'Mod1-A-10k.txt', 'Mod1-A-30k.txt', 'Mod1-B-00k.txt', 'Mod1-B-10k.txt', 'Mod1-B-30k.txt'}
idx=~cellfun(@isempty,regexp(a,'.+(?=00k.txt).+','match'))
b=a(idx)

%or

idx=~cellfun(@isempty,regexp(a,'.+(00k.txt)\>','match'))
b=a(idx)

Just specify your dir query:

list_files2load = dir(fullfiles(directory1,'Mod1*00k.txt'));

that is good idea as well, didn't know I could do that ! selecting the '00k.txt' would be the first loop, then I would pick the '*10k.txt' and so on. So i think the answer of Azzi fits me better.
