Fatal INPUT FILE error, no exon lines in the GTF file: /home/administrator/human/GCA_000001405.15_GRCh38_no_alt_analysis_set.fna
Solution: check the formatting of the GTF file, it must contain some lines with exon in the 3rd column.
Make sure the GTF file is unzipped.
If exons are marked with a different word, use --sjdbGTFfeatureExon .

You can't use wrong type of file. /home/administrator/human/GCA_000001405.15_GRCh38_no_alt_analysis_set.fna is a fasta format sequence file. You need a GTF format file for the --sjdbGTFfile option.
