[maker-devel] Pseudogene identification

[Carson Holt]

The MAKER-P fork was merged back into standard MAKER with version 2.29 (roughly 3 years ago - a separate download no longer exists). This is because MAKER-P’s functionality is almost entirely in accessory scripts and written protocols. The …/maker/bin/maker called by both MAKER2 and MAKER-P is actually the same script. So no need to rerun, because if you are using version 2.29 or later, you already ran it.

Pseudogene calling is therefore handled by accessory scripts and protocols you can find here —> http://shiulab.plantbiology.msu.edu/wiki/index.php/Protocol:Pseudogene <http://shiulab.plantbiology.msu.edu/wiki/index.php/Protocol:Pseudogene>

The other MAKER-P protocols can be found here —> http://www.yandell-lab.org/software/maker-p.html <http://www.yandell-lab.org/software/maker-p.html>

But we want to check whether some annotated genes are Pseudogenes, which lead to the expansion. Do you have any suggestions on this?

Besides, we are not sure whether the default parameters of Maker-P are good for a rodent species. What's more, in my understanding the Maker-P will identify Pseudogenes in the intergenic spaces (which I think the annotated coding genes will be not be tested and checked).
