Data set from example subject

This is widefield calcium imaging data from an example subject. Data from two sessions is included: Septermber 20, 2018 and September 24, 2018. Both sessions are from subject mSM63, a triple transgenic Ai95 subject engaged in a detection task in two sensory modalities; GCaMP6 is expressed in all excitatory neurons. Data collection was by Simon Musall, Rirchard Sun and Steven Gluf. 

Each session contains several files that are used to train the encoding model. The files Vc.mat and rsVC.mat contain the original and downsampled widefield imaging data respectively. This data has also been reduced into spatial components U and temporal components V. The file [mousename]_SpatialDisc_[sessiondate]_Session*.mat contains most of the behavioral information (sensory modality and rate, choice, inter-trial interval, etc.) The Analog.dat files contain data for the piezo sensor (to track hindlimb movements) as well as stimulus onset time. There are also various opts.mat files that contain options used for the widefield imaging. 

The BehaviorVideo folders contain camera data for the sessions (the data has been SVD'ed for both video and video motion energy). This folder also has a file FilteredPupil.mat which contains data for pupil size, nose, and whisker pads. There is also a bhvOpts.mat file which contains some information on how the camera files were preprocessed. 

This file structure can be analyzed with rateDisc_RegressModel.mat to generate estimates of neural activity modulation by task variables, instructed, and uninstructed movements during decision-making.
