===== Overview of data files ===== A promoted (i.e. pre-processed, annotated, and approved) data folder consists of most of the following files: * *.Ncs files: continuously sampled data, "local field potentials" * *.ntt files: raw tetrode files, you will generally not need to load these * *.Nev file: raw Events file * *.Nvt file: video tracking file (usually zipped) The above are raw data files stored by Neuralynx. The following files are the result of preprocessing and annotation: * *.t files: spike times for one putative neuron (output from MClust) * *.clusters: cluster information (output from MClust, you will generally not need this) * *wv.mat and *%%ClusterQual%%.mat files: waveforms and cluster quality metrics * *Metadata.mat file: structured task-related information such as locations of feeders, times of rewards, etc. * *%%ExpKeys%%.m file: basic information about this recording session, such as task, start time, end time, etc. (note this is a .m file, so needs to be run rather than loaded as you would a .mat file) Note the naming convention for the above files: all files are identified by the RYYYY-MM-DD string in the filename, and recording files are further named with the tetrode number. ===== Basic data loading ===== ====== Description of the Multiple-T task ====== ====== ExpKeys ====== ====== Metadata ====== This is example of a Metadata struct, taken from session ZXXX <code matlab> >> Metadata Metadata = Feeders: {[1x1 struct] [1x1 struct] [1x1 struct] [1x1 struct]} Events: {[1x1 struct] [1x1 struct] [1x1 struct]} TimeOnTrack: 627.5610 TimeOffTrack: 3.0261e+03 SwitchTime: 1.7264e+03 goodFood: 'y' Markers: [1x1 struct] Linpath: [1x1 struct] </code>
