Hi Symon,
As I said, the only sort of log file that (PC)Ibex reads is the internal counter. Any other cross-run log system will need to be implemented manually
The results file is written when the submission is sent to the servers, but not read: doing so would publicly expose the results of every participants
Editing a (PC)Ibex experiment means editing the javascript code, that is, the code that is executed on the client side (the participant’s browser). Communication with a log file that persists across runs involves setting up something on the server side, which cannot be done by simply editing an experiment. This is why you would need a parallel setup that would communicate with PennController in some way or another
