Re: [Seqan-dev] Annotation and spliced site

Hi Rene,

github issues seem to one place, but have you guys thought about deploying your own seqan q & a for end users?

It’s like stack overflow but just for seqan

Hi Yue, 

thank you very much for writing us and sorry for keeping you on the loop for so long. 
I'd like you to raise such questions on the issue site on our github page: https://github.com/seqan/seqan/issues.
The mailing list is not-so-up-to-date anymore, and we will probably use this mailing list merely as a news feeder in the future to inform you about new releases or training courses.

Thank you very much for you understanding.

Kind regards,

René

Hi all,

I am trying to use the annotation part of Seqan to solve a question, but I am a little bit confused.

What I want to do is to
1. Read in an annotation file (the format can be GFF, GTF, or BED)
2. Giving two positions (q1, q2) in the genome, decide if (q1, q2) is a known junction.

My Solution:
1. use GffFile in to load the annotation file(GFF, GTF) into a FragmentStore<>
2. extract the exons and create a junction Interval tree using the FragmentStore<>
3. using interval`s 'findIntervals' function giving q1 and q2 to find if there is an interval(junction) exists.

My Question:
1. Is BED better then GFF and GTF in this situation?
2. If BED is better, could anybody give me some examples what seqan data structure I should use to store and do the search? Some pseudocode with seqan data structure and function could be better....
3. If GFF and GTF are better, is my solution correct and efficient? Is there any better way to solve my question? Is there anything I need to pay attention to?

Thank you very much!

Yue Gan
