I have file names such as:
WT 2 b.lsm
And I only want to extract WT or MUT.
In theory I think this should work?!
The idea of the (\s?) is that there might (or might not) be another space, following the first one.
But it stil gives WT 2 instead of WT for the WT 2 b.lsm filename.
Could you tell me the correct syntax?
