Filtering reads on the basis of percentage of ambiguous(N's) characters
... Hi, I want to filter my fastq reads based on ambiguous characters, basically **N's**. So if I have a read sequence having N's greater than 5%, I want to discard that read, if lower than 5%, I want to keep it. It would be really helpful if someone know about any tool which already does that. Thanks ...

... Hi finswimmer, I tried the same thing with samtools rmdup and it considers them as duplicates and retains the one with high mapping quality. Regarding the soft clip bases, I don't think soft clipped bases has to do with this thing because the position 88015806 in the above example is the position st ...

Comment: C: genomeCoverageBed for per nucleotide coverage
... yup, works fine, must say better than genomeCoverageBed because in genomeCoverageBed, if you have all the headers(having all the chromosomes) in the bam file and only a particular chr alignments you want, it still goes through all the chromosomes. ...
