This is because most EST type alignments tend to be partial. MAKER does not try and extend these models, it just leaves them as is, so you will end up with a lot of partial gene models. MAKER will reject est2genome models if they do not have splice sites (unless single_exon is set to 1). MAKER will also not instantiate a model if the ORF is too small a percentage of the transcript. Using something like apollo, you can drag an est2genome alignment into the annotation tier and see what the model would have looked like if instantiated. You will probably see that for the ones that don't produce a gene model that they either have non-canonical splice sites or the longest open reading frame is short.</div><div><br></div><div>Thanks,</div><div>Carson</div><div><br></div><div><br></div><span id="OLK_SRC_BODY_SECTION"><div style="font-family:Calibri; font-size:11pt; text-align:left; color:black; BORDER-BOTTOM: medium none; BORDER-LEFT: medium none; PADDING-BOTTOM: 0in; PADDING-LEFT: 0in; PADDING-RIGHT: 0in; BORDER-TOP: #b5c4df 1pt solid; BORDER-RIGHT: medium none; PADDING-TOP: 3pt"><span style="font-weight:bold">From: </span> Sivaranjani Namasivayam <<a href="mailto:ranjani@uga.edu">ranjani@uga.edu</a>><br><span style="font-weight:bold">Date: </span> Wednesday, 16 January, 2013 9:16 AM<br><span style="font-weight:bold">To: </span> "<a href="mailto:maker-devel@yandell-lab.org">maker-devel@yandell-lab.org</a>" <<a href="mailto:maker-devel@yandell-lab.org">maker-devel@yandell-lab.org</a>><br><span style="font-weight:bold">Subject: </span> [maker-devel] Transcriptome data to gene models<br></div><div><br></div><div dir="ltr"><meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"><style id="owaParaStyle" type="text/css">P {margin-top:0;margin-bottom:0;}</style><div ocsi="0" fpstyle="1"><div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi,<br><br>
I want to generate gene models for all my transcripts (based on just the transcript evidence). To do this I set 'est2genome to gene models' attribute to 1. I have disabled gene predictions from any another sources, that is, I do not provide protein data and
turned off all gene predictors<br>
But I find gene models are not generated for all transcripts only about half of them.
<br><br>
Can you tell me how maker decides which transcripts to predict models for, that is, how is it making this selective decision?<br><br>
Thanks,<br>
Ranjani<br></div></div></div>
