Type Checker Files
Illumina
Non-normalized output data generated by Illumina platforms.
These files are available in GEO as supplementary files, and can be identified by a name like GSEXXXX_non-normalized.txt
This file type contains a data table of probe intensity values and p-values, which is recognized by the pattern below:
NanoString
RCC sample files available in GEO as supplementary files.
This file type has a markup syntax similar to HTML, whose elements contain the headers and the data table of detection intensities and probe identifiers.
<Header> FileVersion,1.6 SoftwareVersion,2.1.2.3 </Header> ... <Code_Summary> CodeClass,Name,Accession,Count Endogenous,GENE1,NM_0001,8 Endogenous,GENE2,NM_0002,5 ... Endogenous,GENE9999,NM_9999,2 </Code_Summary>
NimbleGen
NimbleGen sample files available in GEO as supplementary files.
This file type contains a data table of probe intensity values, sequence identifiers and other annotations associated to each probe.
The last two columns represent values of probe perfect-match and mismatch. An option to remove probe mismatches during pre-analysis is available.
Sequence identifiers may be repeated, and an option to compute average expression values from duplicates is available.
What is a "Type Checker File"?
Type checker files are files created in GEAP Type Checker (TypeChecker.exe). They contain instructions to be executed during pre-analysis in order to identify, validate and process a specific file format.
There are two types of Type Checker Files: editable and compiled.
Editable files (.tcxml) are available to be edited or compiled through Type Checker.
     Compiled files (.gtcheck) are loaded by GEAP and executed when an input file's extension matches one of the extensions from Type Checker file. 
    When the input file is validated and selected by the user, a dialog box with treatment options is displayed. If there is no option, this last step is ignored.
    To install a compiled file, copy the .gtcheck file and paste inside .../GEAP/User/typecheck/ directory. GEAP will read the file on startup. 
    Type Checker Files with duplicated IDs are ignored.
    Hint: Type Checker can be executed inside GEAP through Tools → File Format Checker. This method allows users to test and compile directly into GEAP.
