Dear Colleagues,

We ran an initial analysis launch over the recently produced REST files 
of 2017-01 ver03. It only includes the channels that were studied during 
the workfest. All trees were merged and can be found here:


Examining these, we noticed a loss of the REST output for about 7% of 
the jobs reconstruction jobs. This was the result of a configuration 
change on the JLab farm. The problem was identified and we will resubmit 
the failed jobs.

Once the reconstruction launch is done, we will start a full analysis 
launch with your plugins.

Best regards,
