Hi Brad,<br><br>I apologize for the delay in the response. I've been on holiday for most of the time since you sent your question, and I've just now got back to your email.<br><br>First, I have not used the Staden or BIOLIGN packages so I'm not sure what they can and can't do. I've CC'd this to the help list in case anyone else has input.<br>
<br>GBrowse can display population genetics data such as genotype and allele frequencies, and individual genotypes. The talk you were looking at uses some custom code to show the frequencies. I would be happy to send you the GBrowse config file and some sample data.<br>
<br>However, if I were to do this again, I would probably use the stackedplot glyph (<a href="http://search.cpan.org/~lds/Bio-Graphics-1.981/lib/Bio/Graphics/Glyph/stackedplot.pm">http://search.cpan.org/~lds/Bio-Graphics-1.981/lib/Bio/Graphics/Glyph/stackedplot.pm</a>) or perhaps the HapMap pie or tower glyphs -- take a look at HapMap.org. (I meant to redo this data in September using stackedplot - but that now looks unlikely.)<br>
<br>GBrowse can also show indels, and copy number variation data. Again, see HapMap. <br><br>However, there are a couple things to think about:<br>1) GBrowse is very much driven by the concept of a reference sequence. This reference does not have to be assembled, but you do need to have something that is special to tie all your other annotation too.<br>
<br>2) GBrowse shows alignments, but does not calculate the alignments. GBrowse also does not support editing. <br><br>Please let me know if you have questions.<br><br>Thanks,<br><br>Dave C.<br><br><div class="gmail_quote">

<p>Hi Dave,</p>
<p>I came across your talk on GBrowse (<a href="http://gmod.org/wiki/Image:NGSWithGMODWorkshop.pdf" target="_blank">http://gmod.org/wiki/Image:NGSWithGMODWorkshop.pdf</a>)
while trying to figure out how to compile Samtools for Staden 2.0 installation
(not sure how I got there but it was a good thing I think). Anyway in the
talk you have a couple slides about using GBrowse for pop gen work. I am
interested in this as currently the lab I am in (Dr. Amy Lawton-Rauh at Clemson
Univ.) uses BioLign and since Tom Hall is no longer supporting this software I
have been trying to find a suitable replacement. The problem for us is
that we are a pop gen lab and are always looking at multiple populations of
multiple individuals and most sequence alignment programs can’t handle
this and still edit the sequence. Am I on the right track with
GBrowse? Is this something that may be possible or is Staden 2.0 a better
bet? Thanks for your input.</p>
<p>Cheers,</p>
