Matlab code by Tamar Regev, lab of prof. Leon Deouell, HUJI.
Ran on Matlab 2016b, Windows computer.
Associated with the paper - Regev, T. I., Winawer, J., Gerber, E. M., Knight, R. T., & Deouell, L. Y. (2018). Human posterior parietal cortex responds to visual stimuli as early as peristriate occipital cortex. European Journal of Neuroscience. http://doi.org/10.1111/ejn.14164
This code was written in order to compute visual onset latencies in a specific ECoG patient. There were 3 recording sessions termed here blocks B12, B13 and B14.
Data files are available at - http://doi.org/10.17605/OSF.IO/X3E9R
In order to reproduce the analysis, download all scripts in this repository, and the data files from OSF. The structure of libraries should be as follows -
\MainFolder\
save here main analysis script - MasterScript_VOLST18_GH.m and run it, section by section.
save here also these functions:
PreProcST18_Block_GH.m
procEventsST18_GH.m
procEventsST18_Block_GH.m
onset_detectionST18_GH.m
permutations_noiseST18_GH.m
dataAboveThreshold.m
CSDelectMap.m
Labels_Winawer_ST18.m
PlotOnsetsOrderly_GH.m
inside MainFolder create folder -
\HCNL Lab functions\
save here the following functions, written by members of the lab of Prof. Leon Deouell
HPF.m by Edden Gerber
LPF.m by Edden Gerber
remove_line_noise.m by Alon Keren
ERPfigure.m by Leon Deouell
figextras.m by Leon deouell
varplot.m by Edden Gerber
(see 'HCNL Lab functions' folder on the repository)
download and save in the \MainFolder\ the 3 data folders -
B12\
B13\
B14\
with all of their contents - these are the data structures.

The data is a lightly processed version of the raw data, downsampled from the recording samplerate of 3051.76 to 1000 Hz using the Matlab resample function and rat: [p q] = rat(1000/3051.76); raw_mat = resample(data,p,q);
