Data structure

Input data: .csv file

First column should be named 'identifier' containing the gene/protein names. This column name is case sensitive (lower case letters for 'identifier')

Other columns should be the sample names. Do not include any spaces in the sample names

For transcriptomics, gene names or Gene ID's are welcome, which can be specified later

For proteomics, gene names, protein names or UniProt ID's are welcome, which can be specified later

Raw counts (transcriptomics) or LFQ intensities (proteomics) should be provided. fibeRtypeR will take care of the normalization


When ready: proceed to 'Load Data'

Proceed to 'Fiber type deconvolution' tab after data upload'

Raw data


Normalized data

The average prediction error of FibeRtypeR is ±4% for both transcriptome proteome data (based on RMSE values presented in Figure 1 of our paper).
