## Importing normalized data

You can import normalized data into Chipster, as long as it is tab delimited and preferably log-transformed. If your data is not log-transformed, you can transform it in Chipster using the tool "Change interpretation". In the normalized data file every column must have a name, and the names of the expression value columns must start with text "chip.". Only one title row is allowed. The first column must contain probeset/gene names, and the name of this column must be "identifier". You also need a phenodata file describing your experiment. The easiest way to convert your normalized data to Chipster format and create a phenodata file for it is to run the tool "Normalisation / Process prenormalized". In order to run this tool, you have to import your normalized data to Chipster using the Import tool.

Alternatively, you can modify your data manually to Chipster format, import it directly, and generate phenodata for it using the the tool "Utilitites/ Generate phenodata". If you have already generated a phenodata file in some other program and it contains the right columns for Chipster, you can import it directly and link it to the normalized file by right-clicking on the normalized file and selecting "Link to phenodata"
