Best Cnv Software?

Hello,I know there are many reviews out there, but I can't seem to find exactly what I like.I found this software called mrCaNaVaR, and it's great since it has it's own aligner which is supposed to be...

Samtools Mpileup And Overlapping Paired-End Reads

I am using samtools mpileup to generate a pileup for paired-end RNA sequencing data. I am curious about how samtools handles pair mates whose read mappings overlap. With regard to the simple example...

Paired-End Protocol For Micrornaseq

In another post, a guy wanted to know how to analyze paired-end data and use them to predict microRNAs.I never heard about a paired-end protocol for miRNAseq and would be interested in some more...

Combination Of Paired-End And Single-End Samples In Chip-Seq Tf Study

I have 2 batches of chip-seq samples:(A) One biological SE replicateThis batch, actually, consists of 4 SE Chip-seq samples - one treatment, one control, both have IP controls. All are SE sequenced at...

Does The Mapping Of A Read'S Pair Affect Its Own Mapping Score In Bwa?

I would like to know more about how BWA treats the mapping score of paired end reads. I am familiar with the process used to assign mapping scores by BWA (thanks to this post). I see that the mapping...

Tool: Trim Adapters Of Paired-End Reads (Fastq)

Trimming adapter sequences of paired-end experiments is sometimes a problem. If you clip the mates in two steps, it migh happen that you loose one mate, but not the corresponding one, resulting in two...

In Paired-End Data, If One Read Of The Pair Is Unmapped, Is That Pair...

Hello everyone, I have a simple question about generic paired-end Illumina data. If one read of a pair is unmapped, does this automatically mean that the pair is improper and is (un)flagged in a SAM...

Best way to map paired-end, uniquely mapped reads with Bowtie2?

This has come up before, but I have never been satisfied with, or completly understood, the answers.  My issue is how can Bowtie2 be used to map uniquely mapping paired-end reads (Illumina) to a genome...

How To Determine If Library Is Strand-Specific

Hello all, this might be a very basic question but I gave it some thought and don't see a satisfactory answer.Let's say I have a FASTQ file from a sequencing experiment. How can one quickly determine...

Counting Reads On Paired-End Strand-Specific Rnaseq Data

Hello everybody, I've a strand-specific paired-end library on which I'd like to perform some standard DGE analysis. However I'm quite unclear about how to go about counting reads. Usually when I have a...

Estimating Insert Size From Paired End Data.

Hi,I have paired end data from illumina. To estimate the insert size in silico ( from scratch ), I have aligned the reads as single end reads to the genome ( mouse ). Now I have the two alignment files...

Trimming Adapters For Paired-End Sequences

Hi all,I got illumina paired end fastq files. They told me to trim read 2 at the beginning for ~20 to 30 bp due to the WGA adapters. Can we find the adapters by looking in to the quality? Which tool is...

How To Determine If Paired–End Illumina Rnaseq Reads Are Strand–Specific

I've been provided with more than a billion reads of RNAseq data for a poorly annotated nematode species. They appear to be 2x100 paired-end Illumina reads – I currently know frustratingly little about...

How To Check If Illumina Fastq Is Single Or Paired End With Minimal Sequence Id

Hi all, I am trying to check if a FASTQ is single or paired end. From wikipedia I saw that default format has to be like this:@HWUSI-EAS100R:6:73:941:1973#0/1but in my case the sequence id is...
