Use the GenePattern analysis module ImputeMissingValues.KNN to add the missing data to your gct file. Most GenePattern modules require that all cells in a gct file contain data.

Your original cdt file contained cells that were missing data.

gct file matches the requirements of a gct file in GenePattern.

Save the modified file as a text (tab delimited) file with the name sample.gct.

In the second row, second cell, enter the number of data columns: 44.

In the second row, first cell, enter the number of data rows: 1553.

In the first row, first cell, enter: #1.2.

Add two header rows at the top of the file:.

The gct file format allows for only one row of identifiers.

Delete the second row, which contains array identifiers (AID).

The gct file format allows for only two columns of annotations.

Save the sample.cdt file to your local drive and open it in Microsoft Excel.

Following is a brief tutorial that walks you through this process by converting sample.cdt to :

One common question from GenePattern users is how to convert a cdt file to a gct file. Modules in the Preprocess & Utilities category provide methods for importing and working with data files. Modules in the Data Format Conversion category convert files from one format to another. The Modules page of the GenePattern web site provides a complete list of the modules and pipelines available from the Broad Institute. Review the GCT and RES Files page of the GenePattern protocols.If you do not have a GenePattern account, you can register on the login page. Login to the public GenePattern server.GenePattern provides several modules for creating GCT and/or RES files from gene expression data from various sources. txt extension to the end and doubling-clicking, or (3) importing into a spreadsheet program, e.g. In turn, open these plain text format files using (1) the Open with function and selecting a text editor, (2) adding a.

In Mac OS, to change the file extension, right-click on the file> Get Info, expand Name & Extension section, uncheck Hide extension option, then change the extension in the box provided.

UniquifyLabels and SelectFileMatrix.Īlternatively, you may manually transform files to format-specific plain text files using the following steps:Ĭhange the file extension to the appropriate extension, e.g. ClsFileCreator, or process files in desired ways, e.g. Read_group_trackingToGct, help create supporting files from such expression files, e.g. Multiple modules exist under Data Format Conversion and Preprocess & Utilities that transform plain text files to specific formats, e.g. File extensions appended to the end of a file are recognized by GenePattern modules, start with a period, and are typically three letters, e.g. tab, specific usage for select cells, e.g. headings and numeric tallies, and/or unique sample and probe identifiers.

Required attributes include a specific delimiter, e.g. GCT or CLS, the contents must conform to the attributes of the format as described and have the correct file extension. To transvert a plain text file to a specific format, e.g. Plain text differs from rich text as described in Wikipedia, and these cannot be interchanged.ĭata within files are parsed in various ways, e.g. tab-delimited, space-delimited, comma-separated, or one item per line. Most gene expression data is tab-delimited and you can open the file in a spreadsheet or database program that allows you to export the data into a plain text file. Transforming Plain Text FilesĪlthough different GenePattern modules require different file formats, all of the files are plain text files.

Check their blog for newly added converters. Their Convert file formats page lists supported file conversions, descriptions of file types, and an email to request new file format converters. Exporting Datasets from InsilicoDB to GenePatternĪdditional resources are available from our partnered site GenomeSpace.Importing Data from caArray to GenePattern.Converting Illumina Expression Data Into the GenePattern GCT format.Converting Between MAGE-TAB and GenePattern Expression File Formats.Converting Expression Data into a GenePattern Input File Format.Several video tutorials are also available: This section provides general information to help you create properly formatted files for GenePattern. For more information about a particular file format, select it from the list at the right. Often, one or more of these parameters are input files, which must have a particular format for example, you might need to supply a gct or res file. When you run an analysis module, visualization module, or pipeline, GenePattern displays the parameters for the selected modules.
