subsindex error

In this piece of script I am trying to use a shortcut adapted from another script so that I don´t have to write out each file name I want to import.

     %open right path
      cd (PATHIN)
      %read in all -vhdr files
      list=dir('*.vhdr');

      len=length(list);      
      SUBJ=cell(1,len);

Here I check what SUBJ is and get [] [] as the answer...So then I start the for loop to read in the data:

      for s=1:len(SUBJ)

And it gives me an error which says- Error using subsindex. Function ´subsindex´ is not defined for values of class ´cell´.

I am guessing that when I write

len=length(list);

I am converting the list into a numerical value of the number of files so that are in the directory. What should I write instead?

Thanks in advance for the help! JD

You are trying to access your scalar variable "len" at an index which is a cell array "SUBJ".

If you meant length(SUBJ) instead of len(SUBJ) then you might as well use

for s=1:len

since you have already assigned len to be length(SUBJ)
