•NaviCell Web Service is a powerful data visualization tool that allow users to load, manage and visualize a large number of experimental data types in the context of molecular interaction maps.
•The user can upload expression data for mRNA, microRNA, proteins, mutation, copy-number data, and simple gene lists. The input data format is a standard tab-delimited text file.
•Users can upload sample annotation files that can be used to automatically calculate average values for defined groups of samples.
•Different options are available to display data values: heatmaps, barplots, glyphs and map staining.
Data visualization example
1
Load dataIn the Data visualization menu click ‘Load Data’:Chose File: table in a tab-delimited text file format (e.g. tcga_expression.txt)Name: type name of dataset ( e.g. expression)Type: indicate type of data (e.g. mRNA expression data)Import (several datasets can be loaded one after another)Done
2
Load annotation tableIn the Data visualization menu click ‘Sample Annotations’:Step 1 Chose File: table in a tab-delimited text file format (e.g. ovca_sampleinfo.txt) orSample annotation URL: to upload the annotation fileImport annotationsStep 2 Sample Annotations: Check boxes to create groups (e.g. IntrinsicExprClassJCI)ApplyDone
Step 1Step 2

Check your data
In the Data visualization menu click ‘My Data’:Check available types of data, samples, gene list, group created according to the annotation table, etc.

Expression-map staining
TCGA_04_1332 tetraploid, mesenchymal TCGA_24_1560 tetraploid, proliferative
The patters of mRNA expression visualized as map staining are different in mesenchymal and proliferative types of ovarian cancer samples.

Several type of data can be visualized at the same map using a combination of visualization modes described previous in the tutorial.
In the Data visualization menu click ‘Drawing Configuration’:Step1 Click Heatmap, Glyphs, Map Staining/ click ‘config’ on each one of the configurationsStep2 Heatmap Configuration Editor: follow instructions indicated on the page 5Step 3 Glypg 1 Configuration Editor: follow instructions indicated on the page 9Step 4 Map staining Configuration Editor: follow instructions indicated on the page 11
