How to only extract part of the folder name?

Hi,

I have a folder name: Run 12-27-56.Adaptive PIV.6uqqm6yu

I only want to extract the 12-27-57 (only the nulber part) How would I do that ?

I have like around 26 folfers like that and I want to only extract number part.

Any help would be appreciated. Thanks in advance.

str='Run 12-27-56.Adaptive PIV.6uqqm6yu'

str = 'Run 12-27-56.Adaptive PIV.6uqqm6yu'

d2=digitsPattern(2);

extract(str,d2+"-"+d2+"-"+d2)

ans = 1×1 cell array
    {'12-27-56'}

Here is one way:

folder_name = 'Run 12-27-56.Adaptive PIV.6uqqm6yu';
folder_number = folder_name(find(folder_name == ' ',1)+1:find(folder_name == '.',1)-1)

folder_number = '12-27-56'
