Hello there,
My name is Kaitlin O'Reilley, and I am an undergraduate researcher at the University of Illinois at Urbana-Champaign. I am a new user to FieldTrip, applying it to analyze LFP data from an animal model. The data has already been preprocessed and sampled at 250 Hz. I am attempting to prepare the data with the necessary cfg for future analysis, expecting to get a new data variable outputted. I am using ft_definetrial, and my current configuration structure is as follows:
cfg =
struct with fields:
trialdef: [1×1 struct]
trialfun: 'ft_trialfun_general'
representation: 'numeric'
dataset: 'reworkfirst.mat'
My current issue, appears to be a missing function "printor" in the FieldTrip toolbox. This is the error message I have:
Undefined function 'printor' for input arguments of type 'cell'.
Error in ft_checkdata (line 530)
typestr = printor(dtype, true);
This function "printor" is never defined in ft_checkdata and I also cannot find its location in another folder of the toolbox with "which printor". I've also referenced some of the MATLAB help pages and this has not yielded much success. I know ft_checkdata is nested into other functions called by ft_definetrial
My goal is to accomplish this primary step for future analysis. While it seems like ft_definetrial would be a reasonable option to load the data, I would appreciate to hear if there are other functions that are more effective. Below is a Google Drive link to the dataset I am analyzing. Any suggestions would be great.
