Bedtools intersect A contains B and vise versa

Question

[Medhat]

Is there is any options when using

bedtools intersect -a A.bed -b B.bed

to detect if line in A contains line in B and vice verse "I do not know if -f could help me in this!!"

for example

A.bed

chr1 100 200
chr1 150 300

B.bed

chr1 110 150
chr1 180 350

the result shall be A contains B (assuming I am using -wb)

chr1 100 200 chr1 110 150

What is the expected output ?

[Medhat]

the result shall be A contains B (assuming I am using -wb )

chr1 100 200 chr1 110 150

Answer 1

[PoGibas]

# minimal overlap fraction
# bedtools intersect -f
bedtools intersect -b B.bed -a A.bed -wo -f 1​

chr1    110     150     
chr1    100     200     40

Thanks but it does not work like that , I think the one that will work is,

-a b.bed -b a.bed -wo -f 1

chr1    110    150    
chr1    100    200    40
