Freshly recorded raw data generally needs to go through a number of preprocessing and annotation steps before it is ready to be analyzed. Especially when setting up a new task and/or drive layout, annotation can take a lot of time. If you want to extract spike trains, you will need to spike sort the raw data, which depending on the number of recording sites and the quality of your data can take up to 2 hours per tetrode.
Raw data should immediately be uploaded to the
Incoming folder on the lab database, and backed up to a secondary location such as on your own computer or to DVD.
When preprocessing is complete, the resulting set of files moves to the
Promoted folder. When you promote your first data sets, ask MvdM to verify accuracy and completeness.
We use two different data acquisition systems in the lab. Raw data from a recording session using the
Neuralynx system consists of the following files:
For most tasks, when promotion is complete the following files are also available: The following files are the result of preprocessing and annotation:
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.
