My EEG data

[fongcj]

I have a bunch of text files that have EEG data. Problem is that they are all in hex and I want them in decimal. The format of these files look like this:
5020:30 a6 52
5040:26 cd e4

I know the hex2dec works for arrays in a certain format but I don't know how to put it in that format. Also dlmread with the range function doesn't seem to work for me. Any suggestions?

Read the file in as text, write a parser, in MATLAB if needed or in Perl or c outside of MATLAB. Convert the first column into integer seconds, concatenate the 2nd and third column and then use hex2dec.
