I am new to fieldtrip and I would like to have your opinion about a bizarre error that I find trying to execute the function ft_combineplanar(). What am I trying to do is to obtain the planar gradient from raw data. I use a neuromag306 Elekta MEG system.
I tried to dig deeper into the scripts and I notice some quirks the error could derive from:
1. as soon as I call ft_combineplanar(cfg, data) , data.trials
switches from 840 trials to 192 trials, without any command being
provided that is BEFORE
the first line of ft_combineplanar(cfg, data) being executed! At the same time all data.trials becomes empty arrays
my data structure does not contain the fields 'grad' before
ft_combineplanar(cfg, data) has been called but it does afterwards .
Again this happen without any command having been given
3. The error finally occurs in line 210 of the ft_combineplanar function (indexing error) and it's due to the data.trial array being empty
What do you think?
