how we can get the accession number of an experiment

Question

[zizigolu]

hi,

how I can access the accession number of CEL files submitted by a paper?

for example in "Arabidopsis miR156 Regulates Tolerance to Recurring Environmental Stress through SPL Transcription Factors" how I can reach the CEL files? I read the paper but I could not find any acccession for submitted datasets thank you

Answer 1

Write to the authors?

[zizigolu]

thank you, then the only way is writing to the authors?

You could try a faceted search on the likely databases, but if they haven't given the accession in the paper, chances are they haven't submitted their data. Write to them and CC in the journal – most journals require them to release their data when requested but that doesn't mean they will.

Unfortunately, not all journals ask their authors to submit their data to free available depositories such as GEO. It saves the authors time to not upload the data, so most of them don't do it then (I confess that I didn't submit the data once because the journal didn't ask for it).

They haven't submitted the raw CEL files from the looks of it, but in the supplemental data they've given the fold-change for all (or a large proportion) of the genes.

If it's the sequences you're looking for they explicitly state at the bottom of the paper:
