I need gene lines for compatibility with a pipeline dealing with GTF in Ensembl format. Ideally, I would have gene lines representing the longest transcript - but I am open to discussion about that.Visualize bam file. ggbio supports visualization of alignments file stored in bam, autoplot method accepts : bam file path (indexed) BamFile object. It's simple to just pass a file path to autoplot function, you can stream a chunk of region by providing 'which' parameter. Otherwise please use method 'estiamte' to show overall estiamted coverage. IMO the problem is that trimming the reads with fastp has vandalized the sequence reads beyond recovery. From what you say, it appears that fastp has not just trimmed a few poor quality bases but has removed entire reads, so that some of the pair-end reads have become unpaired in an irregular fashion.

September 10, 2021. I was just doing something similar about a week ago. You may be able to accomplish this using the GenomicFeatures R package. First load up the following in R: library (GenomicFeatures) library (GenomicRanges) library (rtracklayer) Then you will need to get ...The rtracklayer package can parse GTF, via import (). Then you just pass the resulting pieces to makeTranscriptDb (). That latter part is not so trivial though. I recently made the inverse for GFF3, i.e., outputting a TranscriptDb as GFF3 (see asGFF in devel rtracklayer/GenomicFeatures).This page describes how to create an annoated genome submission from GFF3 or GTF files, using the beta version of our process.
