I have a list of start and stop positions of a feature corresponding to a genome. The GTF annotation of this was generated in house. I have since made a transcriptomic fasta file from the genome fasta and the custom GTF. I would like to use a tool that looks at these features in the transcriptome but I have only the coordinates in the genome (transcript_id, chr, strand, start and stop) so is there any tool that can convert these features into one for the transcriptome fasta file (transcript_id, start and stop)? If there is a way to do it in bash, python or R, that would also be useful!
Many thanks in advance.
