extendedSequences length is not the required for DeepCpf1 (34bp)

Hi, I’m using CRISPRseek dev v. 1.35.2, installed from github (hukai916/CRISPRseek). I wanted to calculate the CFD, and the grna efficacy of a Cas12 sgRNA (my_sgrna.fa file) using Deep Cpf1. my_sgrna.fa, TTTT (PAM) + sgRNA (20bp): >sgrna1 TTTTTGTCTTTAGACTATAAGTGC Command: offTargetAnalysis(inputFilePath = “my_sgrna.fa”, format = “fasta”, header = FALSE, exportAllgRNAs =…

DESeq2 and high prefiltering cutoff

DESeq2 and high prefiltering cutoff 1 @255004b1 Last seen 3 hours ago United States Hi, I am curious about prefiltering with DESeq2. I understand from this site and reading the DESeq2 vignette that prefiletering is really unnecessary as DESeq2 has a stringent filtering that it does. However, I’m seeing better…
