The MIMIC-III dataset (v1.3) consists of 26 comma-separated-value (CSV) files, with text strings surrounded by double quotes. After download, the files can be decompressed using the command-line tool gzip ('gzip -d *.gz'). Two checksum files are provided to allow data integrity to be checked before and after decompression (for example, by running ""md5sum -c checksum_md5_unzipped.txt"" from the command line).
