Precision steering of current in macaque M1 using multi-channel non-invasive TES - Single-Trial Tensors

Each .mat file contains tensors of electromyographic responses to transcranial electrical stimulation, synchronized from two TMSi SAGA-64 acquisition devices. The primary data variable is `X`, which is organized as `nTimeSamples` x `nChannels` x `nStimuli`. Time-zero for each stimulus was considered the rising edge of the first pulse in a pulse sequence. Times are given from 20-ms preceding the pulse onset to 40-ms following the pulse onset. 


Several accompanying metadata variables in each file indicate the correspondences between rows and relative time-samples; channels and columns; and which individual responses belong to which stimulus pattern. 


In addition, the ROI and segmentation used in the modified `ROAST` pipeline for post-hoc finite element analysis is included in the `.nii` files. Because reproduction of all mesh/stimulus combinations is time-consuming, summary gifs for all patterns in the HP10 and HP20 pattern sets are also included.
