Re: Disk Set 18 Arrives

[Glenn Gombert <glenngombert@hotmail.com>]

Hi Tom,

I just got my set of Disk 18 data right now...I am trying to get Michael's 
pipline running on my Linux system here (I just sent him a question) I would 
like to try and process your Disk18 dataset as soon as I can get it 
configureed here....
