How to correct single nucleotide variation due to PCR bias ?

Question

[Gautier]

Hello everyone,

I'm having a hard time to find how to merge my data when I have a single nucleotide variation. How can I tell my Rstudio script to merge my data when I have only a single nucleotide variation (that I consider due to a PCR bias amplification of my library) ? I would like to merge the data to rows that have the highest clonal rate, like this :

cloneFraction nSeqCDR3

0.3520491020252197 TGTGCCAGCAGTTTGAATTTAGCGGACGGTGAAGCTTTCTTT 0.0324321742453190 TGCGCCAGCAGTTTGAATTTAGCGGACGGTGAAGCTTTCTTT

so I have :

cloneFraction nSeqCDR3 0.38448.... TGTGCCAGCAGTTTGAATTTAGCGGACGGTGAAGCTTTCTTT

Thank you for your help, I know how to merge but I'm looking on how to tell the script to merge when only one nucleotide is different.

Regards,
