Accessing the information available in the GEO database [Programmatic access for GEO database]

Question

[startup_biostar]

I am trying the access the information available in this GEO link http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSM1289257 through API Entrez - Eutil.

So, I use their pipeline to access the data

Link1 : http://eutils.ncbi.nlm.nih.gov/entrez/eutils/esearch.fcgi?db=sra&term=GSM1289257

Link 2: http://eutils.ncbi.nlm.nih.gov/entrez/eutils/efetch.fcgi?db=sra&id=562544

There is some information missing in this particular way of accessing the data.

For example, In the first GEO link,

But I am seeing the information like Treatment Protocol, Growth Protocol, Data Processing in the eutils result that I got accessing the Link2 above.

Even I tried changing the eutil database as gds

Link1: http://eutils.ncbi.nlm.nih.gov/entrez/eutils/esearch.fcgi?db=gds&term=GSM1289257

Link2: http://eutils.ncbi.nlm.nih.gov/entrez/eutils/efetch.fcgi?db=gds&id=200053268,200053313,100013821,301289257

Not much details in there.

Am I missing something or how should I access these information of interest.

Thanks

This post is the answer to your question to some extent:

Other useful posts describing how to reach some information from GEO, either programmically or not:

What is the information of your interest,

it's not very easy to understand: yeasts and Rna-seq tools? Is it correct?

And a lot of data are pre-processed and ready to analyse with known tools.
