I have just the same code as you, but MATLAB gives sometimes error with files which work fine if I load them in one by one :s
If my ascii-file is named 1_01.txt everything works fine, but if I use 2_01.txt it gives a fellowing error;
Error using importdata (line 137)
Unable to open file.
Error in ScienceWeek (line 11)
log = importdata(fnames(k).name);
Do you have a clue what is going wrong?
