MeV is capable of loading genomic data from many different types of files. Affymetrix, Agilent, Illumina, GenePix and others are availble.  MeV also supports several platform-independent file formats such as TDMS, MAGE-TAB and GEO.

The Tab-Delimited Multiple Sample (TDMS) file loader.Tab-delimited Multiple Sample files

Download an example file

Loaded with the TDMS file loader. This file format is a flexible, vendor-independent format where each row contains a record for one gene, with samples arranged by column. Any number of gene or sample annotation rows are allowed. MeV will attempt to "guess" which rows and columns contain annotation and will color-code them accordingly. Please verify that MeV has guessed well. If it has not, click to select the upper-leftmost cell that contains expression data. MeV will re-color the cells to reflect your selections. Gene annotations are colored blue/purple, sample annotations in blue-green, and sample annotation headers are in yellow. Expression values are striped in blue and white.

MAGE-TAB Files

Sample IDF file

Sample SDRF file

Sample Data file

The MGED consortium has written a generalized file format called MAGE-TAB. MeV's MAGE-TAB file loader accepts the MAGE TAB idf, sdrf and data files, though only the data file is required.

Other Methods

Data can also be loaded into empty Multiple Array Viewer windows with the Gaggle framework. See the Gaggle tutorial for more details.
