I have a list of illumina gene id's that I want to perform some operation, in order to do that i need to convert the illumina id's to their official gene symbols, I have tried the following :
- using the platform information from GEO ->failed, contain some gene name as unigene id.
- tried to separate out those unigene id's and map them to official symbol-> failed because most of them do not have a official name as per org.hs.eg.db and some of them have more than one name.
I am using RStudio , I cannot choose which gene symbol to choose and how ? I have use AnnotationDbi::select() funcion followed by split() to get individual id's, but I am stuck here :
UNIGENE SYMBOL GENENAME 87 Hs.112482 NAALAD2 N-acetylated alpha-linked acidic dipeptidase 2 88 Hs.112482 CHORDC1 cysteine and histidine rich domain containing 1`
also I tried using illuminaHumanv4.db, that too failed for not having all gene information, please help how to proceed from the above step.
