Hi
I was trying to find the sequence of a gene and its exons in the
underlying clone using the ensembl api and not getting very far. I was
doing this to get used to the api more than anything else and trying to
map between a gene which is on the reverse strand, and a clone
containing the forward strand.
I was able to retrieve the coordinates of the exons in the genomic sequence.
exon 1
start: 128,684,354
end: 128,684,488
exon 2
start: 128,664,422
end: 128,664,818
I have to flip the start and end round in my head
forward 5' ===========================================3'
reverse 3' ===========================================5'
126,664,422-128,664,818 128,684,354 -128,684,488
<=========E2 <=============E1
But i then was lost how to map these to a clone. I looked for something
equivalent to the TranscriptMapper but couldn't find anything.
The total length of the sequence (including the intron in the middle is):
128,684,488 - 126,664,422 = 202066 bases
I then want to find out how these entire region maps to the underlying
clone (AC112484.8). I would then like to print out, from the clone, the
appropriate subsequence in both the forward and the reverse direction.
I hope that makes sense. I don't think it should be difficult but I
can't find the appropriate methods
Many thanks
