My group sequenced multiple hotspots of a panel of genes. Now they want me to create a list with what it is sequenced, with the gene name, the exon and the codon number. I have reached the point to know which are the exonic parts of the bed file, but I am having struggle to associate this data to the main isoform of the gene and the exon and codon number. I am using UCSC Browser, but maybe other software works better. Can you please help me?
