Hello,


I have been looking at the SRA (Sequence Read Archive) SQLite database

provided as a Bioconductor package for R.


My question concerns top-level studies, which are found in the study table

and dated in the submissions table.


The question is why are there so few entries for the top level studies for 2013

as compared with 2011 and 2012....


The SQL queries I have written, joining the Submission table and Study table

in order to obtain the submission_date yield the following counts of top-level

studies by year....


2005|64
2006|38
2007|94
2008|269
2009|893
2010|2631
2011|4077
2012|5208
2013|724


As one can see the number of studies in the meta-data falls off on 2013.

I have been using the sraDB bioconductor SQLite database which has

the creation timestamp of 2013-12-03 08:29:26 in the metaInfo table.


Would really appreciate if anyone has any useful thoughts on this.


Best regards,

Jamie
