How does one interpret the output from a 'PGLS-Relationships' analysis in Compare 4.6b?

04 April 2015 0 3K Report

The output includes results for PGLS at a given alpha value, Felsenstein's independent contrasts and TIPS (where phylogeny is not accounted for). In my case, mean PGLS carries high alpha values and both FIC and TIPS have alpha values of 0. Should I simply focus on the PGLS and treat the others as hypothetical scenarios? Should I use the PGLS alpha as my guide for acceptance/rejection of the other two? Or alternatively, should trust be given to the set with the highest likelihood? Also am I correct in stating that R^2 measures the extent to which phylogeny accounts for the observed correlation?

For a PGLS analysis in Compare 4.6, can anyone propose sources of error or solutions for the following problems?

I am using Compare 4.6 software to perform PGLS on a large set of trait values using a known phylogeny (based on genetic distance; Taxa = 23, Traits = 110, phylogeny = 1). The problem is that when...

RAPD PCR: does every sample require a technical replicate or will a subset suffice?

In the interests of conserving time and resources, I would like to avoid performing replicates on every single sample, unless this is absolutely necessary. I have read in the literature that 5-10%...

Can you re-position a DNA ladder in a gel picture (you plan to publish) using image editing methods?

I am thinking about publishing work based on RAPD PCR. The problem I am having is that my gel pictures consist of several different experiments/primers (represented by 10 samples each) beside a...

Can anyone provide an example of an input file for the program DfDist (Beaumont, 2008)?

The program detects loci influenced by selection by comparing their Fst values to a neutral simulation.

Could anyone give an example of AFLP presence/absence data written in Genepop format?

I have seen examples of the Genepop format, but never for dominant markers. Could anyone, additionally, provide a clear explanation of the format's characteristics?

In what format should AFLP data be submitted to software used for detecting selection?

I am aware that the detection is based on Fst values. However, should these be obtained using another program and then be transferred to DfDist, Bayescan etc. or should AFLP binary data be used...

In preliminary screening of AFLP primer combinations to determine pairs which give optimal results, how many individuals should be screened?

Is this randomly decided by the researcher or is there a general principle they can base their decision on? I have read many papers looking for an answer but have yet to find an explanation on...
