I have a list of Gene IDs from human, I would like to convert it to Affymetrix IDs,
examples gene IDs
GNAI1 HLA-DQA1 WDR1 LTBP2 MXRA5 MMS19 SEC13 C6 IL16 FAM82A1 GBE1 TUBAL3 CYB5R3 ANXA1 APCS COL14A1
Do you know how I can do it in R and based on website?
I have tried the following ID convertors online but none of them worked
David only convert to three Affymetrix such as 3PRIME_IVT_ID, EXON_gene_ID and SNP_ID
I also tried Ensemble Biomart like below but did not convert anything
1- first I web to website
2- select " Ensemble Genes 78" and "homo sapiens genes (GRCh38)"
3- then click on "filter" ------> "gene" -------> and then paste the example list of genes there
4- then "Attribute" ------> "External" ------> and select "Affy HG U133A probeset" Then click on "Results" but nothing showed up
