SRMA memory leak

03-02-2011, 02:46 AM

Hi friends
Was anybody successful using SRMA? I have tried it with the RANGE option sa well, and it has worked for chr1, but I get the error with chr2.. Here is the error (RAM we have is 140GB) after that srcript is hanging:

From Collection to Sequencing: Why Sample Preparation and Preservation Define Sequencing Data

by SEQadmin2

Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.

The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.
