See later: Could we add a bias by placing the trusted RRI in the middle of the context and possible negative interaction could be at the border of the context? Shoudl we disallow RRIs in the bignning and and of the sequences?
Is it a week spot that we have the proteom m-RNA binding data? Are there many proteins binding to ncRNAs?
concerning
extrect genomec context for trusted RRI's (e.g. 300 on both sides, context lenght depens on length of RRI and RBP interactions sides)
I would always add the same context length left/right independently of the RRI/RBP subsequence length. simplifies the setup and sequence length is of no matter anyway...

good point! can be solved by constraining the seed to the positions +100 to (length-100), i.e. similar to the positive data set but with the additional "blocking constraints". that way, the accessibilities of the RRIs should be reliable than those around sequence ends!

I would guess RBPs do not distinguish much between lnRNA and mRNA...

Ja sorry I wanted to check the length of RRI and RBP binding sides to see if 300 context is long enough. But of course, the added context will be for all the same. Maybe I should have made this point more clear.

I was just wondering since the data of the paper I found only gives us the proteome binding m-RNA, if I understood it correctly.

most likely they were just interested in direct gene regulation, i.e. mRNA binding
Two latest attempts to make the positive and negative feature distribution more allike. (1) Using occupied regions as contain also for the positive instance generation -> We are losing many sequences but the distribution looks a bit more similar than without using it. (2) not allowing long bulges within the interaction
bin gespannt... :)
Idea: Adding Context to the 'trusted RRI' to generate from these sequences the positive and negative instances using IntaRNA. The positive data will be generated by calling IntaRNA setting the --seed[Q,T]Range to the HTS found interaction side. For the negative RRI instance generation IntaRNA is called by constraining the regions, that are known to be part of an interaction, and therefore should not be part of the predicted RRI (--[q,t]AccConstr="b:start_1st_blocked_side-end_1st_blocked_side,start_2st_blocked_side-end_2st_blocked_side,...")
