pygaze analyser with existing edf files

[mforloines]

I want to create heatmaps from existing data not collected with pygaze (rather collected via python and eyelink). I am stuck trying to figure out what the required .txt file is supposed to contain as one was not created when I collected the data. I ran the example (slideshow) and tried to reconstruct a .txt file from that example, but ran into this error when I ran the analyzer script with my data:

saccades = edfdata[trialnr]['events']['Esac'] # [starttime, endtime, duration, startx, starty, endx, endy] IndexError: list index out of range

Any help is appreciated.
