It looks as if you are using the Extract DNA tool? GTF/GFF files have
coordinates with a 1-based start position - and this was your input, but
the output from this tool produces coordinates with a BED-style 0-based
The genome index files used by the tool are in .2bit format and the
source is encoded into the full name. The sequence content of the
reference genome is not altered by the tool. Perhaps the interpretation
of the coordinates is the source of the difference or you are sourcing a
different version? If you have a question about where we sourced a
genome, please let us know.
To see a quick description of both BED and GFF format together in the
UI, click into the tool "Convert Formats -> GFF-to-BED converter". For
more in-depth descriptions, please see our wiki:

I ran a preliminary analysis using test genome and gff file. But the
results is confusing me.
The fasta file is
The gff3 file is

The output is
1 From the gff3 file we can see the start and end position is 5 and 15,
why the start and end coordinate is 4 and 15 in the output file, which
is really confusing.
2 How does the galaxy treat the genome file, are all the characters
except for ACGT are removed from the genome file? Because I use substr
function in Perl to test the output of galaxy, somethimes, there is
I really appreciate all your help.
