Hi everybody im quite new to Matlab.
How is it if you have like 1000 files. Do you first convert them to char characters? when i do it with one file with the name '20191108_1_blank_BA_pos.mzXML' as follows:
it gives me the 3 letters before _BA, here "ank".I want to find the 3 letters before _BA for all the files. The code above allows me to do this for one file. Do i have to do a for loop and is there another ways instead of converting the files to type char?`
Thanks a lot!
