Trouble using fopen

I am trying to do batch processing. The list of text files to be processed are in a text file which I am able to read into a string. If I try to run fopen again by passing the string as the argument to fopen, fopen fails saying : No such file or directory. Instead, if I hard code the filename in the fopen statement the file is opened successfully.

EDU>> fopen('./nmos_1_50n.dat', 'r')

ans =

       5
  EDU>> mystring

mystring =

nmos_1_50n.dat
EDU>> [fid2, msg] = fopen(mystring, 'r')

fid2 =

      -1

msg =

No such file or directory

      Please help.

We cannot tell from here whether mystring might have trailing blanks.

Thanks for your suggestion. I realized I had to remove the trailing blanks using the function deblank()
