In general, genome wide genotype data (SNPs) goes through the following processing steps:[[BR]]
1. Genotype calling[[BR]]
2. Cleaning of the genotype data[[BR]]
3. Imputation (optional)[[BR]]
4. Analysis

Steps 1-3 can be regarded as preprocessing steps, while step 4 is one that can be re-iterated many times, based on a single outcome of steps 1-3.

Steps 1 and 2 can be combined in a single software package.[[BR]]
Step 3 is performed using imputation software, such as IMPUTE, Beagle or MaCH.[[BR]]
Step 4 combines the cleaned (+imputed) data plus some phenotype data into an analysis.

An automated pipeline may be desirable. Steps 1+2 could be standardized and thus also automized into a pipeline. Step 3 may be added to that.

Step 4 probably has to be in a separate pipeline. This would result in a kind of platform (based on Molgenis?) in which researchers construct instructions in order to run some analysis.[[BR]]
Results come back to the platform and can be inspected.[[BR]]
An important ingredient of whole genome SNP analysis is the command line program PLINK. Information about that can be found below.
