Pindel Is Not Detecting Long Insertions

Hello,

I am using pindel to detect long insertions, but it doesn't detect anything in any of my samples. However it detects inversions when I say to it not to put it. Why could be this? I called it in 250 samples where I know there are long insertions.

arctic monkeys do i wanna know concert

./pindel -f $ref -i $inputfile -o $output  --report_interchromosomal_events false --report_duplications false --report_inversions false

is there any other software a part from breakdancer and pindel to detect long insertions?

Best regards

pindel

how long are your insertions and what is the read length? Pindel finds insertions with maximum length of ReadLength - 20, if it needs some bases to align to the reference. if you do not need breakpoints and the sequence inserted, read-pair approaches like breakdancer is the choice. but again, there is maximum size limit for insertions detected by read-pair approach as two reads in a pair must span the insertion: InsertSize - 2 * ReadLength.

you will need local assembly if your insertion is longer than the read length.
