[BioC] Error working with indexes in htf5 files

[Maria Pedroto [guest]]

Hello,
I'm trying to use the rhdf5 package to read and iterate in a hdf5 database. 
The structure of the database is of a simple table of 13 columns with two of them being indexes.

I'm not being able to find out how to use the indexes to find the information I need. That is, I think i need to access the timestamp index and return a value to be inserted in the h5read function at the index field. 

Dunnow if i'm using the best function because I haven't found on the web an example so complicated. 

Best regards,
Maria Pedroto
