Using GFF3Writer in Biopython
... Hi all, I am having trouble figuring out `GFF3Writer` tool from `Biopython`. I have a regular ensembl `gff3` file and want to extract only certain types of features. I get an empty gff output with only one header line. What am I doing wrong? Here is my code below.: ``` in_file = "test.gff ...

Comment: C: Difference between Allele frequency spectrum and Joint allele frequency spectrum
... My explanation is very simplified, I just made it to be intuitive. Furthermore, I guess these numbers may be log-transformed for plotting, and I don't remember exactly what they did for these figures. AFS is estimated from allele counts, i.e. how many times you see a SNP in a population. 20 chromo ...

How to check if BAM is indel-realigned?
... I have a few BAM files from collaborators and I do not know if these were indel-realigned. People who was working on these files are no longer working in the lab, so I have no sources of information about details of these alignments. Is there a way to check if these files were indel-realigned? ...

Answer: A: Difference between Allele frequency spectrum and Joint allele frequency spectrum
... Joint allele frequency spectrum is allele frequency distribution calculated between two\three populations. Imagine a 2D plot, where on x axis is AFS of population 1 and on y axis is AFS in population 2. For example, you can plot derived allele counts in Yoruba versus Central European population. Le ...

Simulate genotype likelihoods
... I am looking for a package to simulate genotype likelihoods using a vcf file. Something similar to ANGSD tool http://popgen.dk/angsd/index.php/MsToGlf But instead of msms input, I have simulated vcf files. I was thinking to simulate reads (using the vcf) and then call genotypes and GL. But maybe th ...

Answer: A: Completely confused about terminology and what I'm actually analysing here
... 1) some of them probably are, some are probably not, if these are published, all info should be in the paper; 2) I am not an RNA person, but any aligner, such as bwa, should work; 3) I guess it depends on your data and goals of the project. You probably should get some theoretical knowledge in RNA ...
