MATLAB-based logfile parser for 2.4 combat logs

Well, I was bored, so I wrote a quick and dirty log parser to pull data into MATLAB and split it out appropriately. It doesn't "do" anything yet, because I haven't created any subsidiary functions (things like - show me person N's total damage dealt, for example), but it gets the data in in a raw format where you can manipulate the data to your hearts content.

For example, after running the importer on a 5 hour log of Kalecgos attempts I was provided with, I could filter out Spectral Blast debuffs, retrieve the times when a Blast event was received, calculate the delta between blasts, filter out very short (to remove splash blasts) and long (to remove 'inside' and wipe deltas), and get a very reliable value for time between portals (which is not fixed, for the record).

Or for amusement, maybe I want to check how many 'not enough rage' messages my tank Teepz generates, typically.

sum(find(strcmp(sourcename(find((strcmp(aura,'SPELL_CAST_FAILED')))),'Teepz')) ~= 0)

As it turns out, over ~5 hours, he generated 4537 of these. Or roughly 1 per 4 seconds. Of course, that includes wipe and recovery time. I don't have parsing functions created to generate values for those.

Or, after pulling it in, if I want the more traditional things like "How much damage did player N do with autoattack", I'd do the following.

teepz = find(strcmp(sourcename,'Teepz'));
swings = find(strcmp(aura,'SWING_DAMAGE'));
c = intersect(teepz,swings);
cellamt = amount(c)';
teepzdmg = 0;
for i = 1:size(cellamt,1)
     teepzdmg = teepzdmg + str2num(cellamt{i});
end
teepzdmg

It's by no means a WWS replacement as is, but it'd be easy enough to write one - however, for the MATLAB savvy, you may find it useful for looking for more abstract things, things that WWS doesn't track, and fight analysis on new content where you may be more interested in "When did event N occur?", etc.

Anyway. Play with it - if you get something useful, post it.

(Rename the attached file to .m in order to get MATLAB to recognize it as a script, of course.)
