Mapping against a Trinity genome assembly? #303

Open Trinity2018 opened 1 year ago

Trinity2018 commented 1 year ago

Hi there,

I'm working with multiple RNA seq samples. These samples belong to bird blood infected with malaria parasites. The genome reference for the parasite species is not available. Most of my reads belong to bird and I'm not interesting on them...only parasite.

I have created one single de novo assembly through Trinity based exclusively on parasite reads. So, the assembly has only parasite contigs and that's why I do need to run the analyses with it.

I'm interesting on genetic variation of my parasite population through analyzing SNPs. After reading what Phyluce can do, I have some questions:

In phyluce... 1) Can I use my Trinity assembly for mapping? I do NOT have a .gff file or similar... 2)Can I made SNP analyses with 42 samples ? I know they are a lot, but maybe I need to do it by groups?

Any help is more than welcome.
