text: user872: I am a student trying to analyze GEO2r datas for one of my courses.
  The IDs given in the output are different for different series. I need to convert all of them to a similar format.
  In this process I encountered the following type of ID which I don't know its origin:
  ”ID"    "logFC"
  "SP_v2 4634"    "-0.9897758"
  "SP_v2 3382"    "-0.8391782"
  "SP_v2 4210"    "-1.1693583"
  "SP_v2 2117"    "-1.0504727"
  "SP_v2 3488"    "-0.9756444"
  "SP_v2 1128"    "-0.8289103"
  "SP_v2 2735"    "-0.8629999"
  ...
  
  Each one of the rows represent a single gene.
  My question is that what is this ID? The GEO accession is GSE97750.
  
  user194: This is possibly a wild goose chase, but a lot of searching led me to this sample: 
  https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSM2536852
  Which appears to exhibit accessions of the right format. This in turn leads to the platform:
  https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GPL22166
  Which is a custom spotted cDNA array, which the metadata seems to suggest is a human platform.
  The full annotation table gives gene symbols and Entrez IDs for most of the probes on the array:
  https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?view=data&acc=GPL22166&id=53508&db=GeoDb_blob144
  To take the example of the first line of your results:
  ID          ORF     Entrez gene SEQUENCE
  SP_v2 4634  ETNK1   55500       AAAGCAGCTTCATCTTTCAAAATTGATTTGCTCTGGTTTT
  
  The Entrez Gene record for that ID matches up:
