How can I identity Branch point sequence from Intron?

Question

[praasu]

Dear All,

I have DNA-seq and RNA-seq of novel protista. I have assembled the transcripts with Stringtie and extracted the list of intron. I would like to predict branch point sequence, I would like to know, if there is any tools or pipeline to predict the branch point sequence is available. Please let me know if anybody has some suggestion?

Thanks for your time in advance :)
