Processing Multiple EMG files

I have multiple files of raw EMG data of different muscles that needs to be linear enveopled. I know how to do that and have made code for it but I was wonderig if there would be a way to run the code on multiple files to save some time. I know that a for loop of some sorts could be used but I do not understand how to create one for files instead of vectors. Is there any way to do this?

ex. the files can be found in 'C:, User, User1, Downloads, S02, S2_T3data, Proceessed_EMG, Cond_EMG "

the files are named : SCM_L, SCM_R, UTR_L, UTR_R

Thanks in advance

"Is there any way to do this?"

Of course:

You will probably need this too:

So for this method, I would have to rename all the files to have numbers, correct? So like SCM_L1, SCM_R2, UTR_L3, UTR_R4

No. That page illustrates two basic approaches, neither of which require you to rename any files:

• use dir to get a list of the files and iterate over that.
• generate the names (which could be via indexing from an array or some other algorithm to create the names). This approach might suit your filenames, which seem to be combinations of two sets of strings.

You certainly do not have to number the filenames.

I have tried to use the dir function to get a list and I keep getting an error

Error in ForLoopPractise (line 2)

dir Users\ryanchhiba\Downloads\S02\Subject 2_VTAS

CA_JTTT_T1_Feb_23_2021_conditionedEMG.Processed_EMG.EMG_Processed.Conditioned_EMG

dir Users\ryanchhiba\Downloads\S02\Subject 2_VTAS CA_JTTT_T1_Feb_23_2021_conditionedEMG.Processed_EMG.EMG_Processed.Conditioned_EMG

thats the path, is it becase the Subject 2 file is a MATLAB file and I am looking for things in MATLAB?

Do not use command syntax, use function syntax exactly as the example in the documentation shows.
