Procedure for inferring signature contig expression in an independent validation dataset. The colored contig from the signature is quantified in the validation cohort by extracting all its constituent k-mers and retrieving the corresponding k-mer counts from validation k-mer count matrix. The count vector of the contig in each sample of the validation dataset is taken as the median of counts for k-mers in this sample
