About alm-2.

Summary of the data

This is the calcium imaging data set described in Li, N., Chen, T.W. et al Nature 2015. These dataset contains calcium imaging data from the anterior motor cortex (ALM) in mice performing a tactile delay-response task. The raw data consists of images, while the processed data consists of fluorescence transients of individual ROI, the identity of imaged cells (PT or IT), and behavioral variables (object location, licking direction etc.).   The data is from four animals and includes 59 recording sessions.  Results from the experiments are described in:

Format of the data

For each session there is a matlab file containing the meta data describing the session and another matlab file containing the processed data.  In addition, all of the original raw imaging files are provided in .tif format.  Total size of all the matlab files is about 580MB.  Total size of the raw image files is about 201 GB (compressed).  Matlab scrips to generate some figures in the Li, Chen et. al. 2015 (Nature) paper are included.  Details of the data format are in the data description document.
