I am working on a microarray analysis using Agilent data (SurePrint G3 Mouse GE 8x60K IDs e.g. A_30_P01020727), having the list of Probe IDs with it´s corresponding statistics and fold changes. My goal is obtain the corresponding RefSeqmRNA from NCBI to anotate them afterwards.

So far, I have tried different approaches combining several databases and internet searching tools without succes. I would like to know the best way to achieve this efficiently. I am open to using languages like R, and any suggestions on libraries or packages that can facilitate this process would be greatly appreciated.

Could you provide me with a guide or code examples to annotate Agilent identifiers and map them to RefSeqmRNA from NCBI?

Thank you in advance for your help.
