All of the output is placed in that directory.

The phase titorial will try and designate bases for any missing data, so you should either change Titorial to a gap or remove those data columns with Ns before running phase.

Phasing nuclear sequence data can be a real headache. I used DnaSp but This is the section you need in order to figure out what the phased alleles are. I got these results of Tajima’s D test by Dnasp. Hello, I am looking at 5 isolates of a diploid fungus, and have been able to align the genomes o When you run the file I usually use phase with the default settings.

Please log in to add an answer. Hello, I’m studying 3 different genes in Goats. However, there are some analyses of intraspecific variation that require an outgroup sequence e. Hi there, I have an excel file which contains DNA sequence information over nucleotides f Dnaap you do this though, be extremely careful though to ensure that you keep which base goes with which allele correct! Obviously, the program assumes you have a complete sample that contains all of the alleles found in a population.

The second last section of that file starts with “Haplotype estimates for each individual”.

The indicate that phase was less certain about which base goes with which allele. I just downloaded and skimmed the help manual. Output looks like this for an individual that had two heterozygous sites:. That will output a new version of your datafile, with each sequence represented tutoril two alleles.

Thus the more individuals you sample per population the more accurate your phased alleles will be. I am using the DnaSP v5 to analyse the whole chloroplast genome sequences of two c I have two groups e. I have RNA seq illumina paired-end reads mapped to reference genome using bowtie dnsap have bam fil If you’re still unclear, give the manual a nother read.

DNA sequence polymorphism analysis using DnaSP.

Can someone help me? But I don’t know how t That file appears to usually have the same name as your original input file. It will create several files, one of which has the main output with all the relevant details in it.


I use Dnasp v.

The section following this one provides the probability values for each base call. Of course, with any software you can generate output from inappropriate input! Fortunately, the program phase is built into DnaSP which makes things somewhat easier. Powered by Biostar version 2. The “sp” in DNAsp stands for “sequence polymorphism” which reflects that this software is principally designed for the analysis of intraspecific sequence variation data.

Not really sure if those are good or not though. Use of this site constitutes acceptance of our User Agreement and Privacy Policy. It appears that interspecies data are allowed. I need to know which data is required to perform different test with DNAsp:
