Fpkm to fold change
WebJun 22, 2024 · We compared the reproducibility across replicate samples based on TPM (transcripts per million), FPKM (fragments per kilobase of transcript per million fragments mapped), and normalized counts using coefficient of variation, intraclass correlation coefficient, and cluster analysis. ... which are gene-wise log-fold change quantities … WebGenes that were considered to be strongly induced when they followed the criteria of FPKM ≥ 10, fold change (log2) ≥ 2, p ≤ 0.01, are in bold. Induced genes followed the criteria of FPKM ≥ 10, fold change (log2) ≥ 1, p ≤ 0.01, and are underlined. Fold change and p-values were calculated with DeSeq2 (Love et al. 2014)

The addition of 0.1 to the FPKM value was done in order to include observations of zero in further analysis. Students also calculated a log 2 fold change (Log 2 FC) value for each gene (Eq. 2) and then converted this value to linear fold-change values (2 Log2FC).
