License count is made by ssh'ing to surfer, then

cd /home/httpd/FreeSurfer/customers

and each ???? and ????? file is a license. To license count by year, ex. 2014:

ls --full-time * | awk '{print $6}' | grep 2014 | wc -l

and this is a loop which regenerates the table data above:

@ total = 0
foreach year ( 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 )
set count = (`ls --full-time * | awk '{print $6}' | grep $year | wc -l`)
@ total += $count
echo "|| $year || $count || $total ||"
end

Mailing List

Subscribers

last updated 2 Oct 2013'

There are 1875 freesurfer mailing list subscribers (includes those who do not receive messages but can post).

To determine this number, login to the administrative interface of the freesurfer mailing list, click 'Membership Management', and the total number of users is shown italicized in the middle. This number includes those who have opted to not receive the mailings. To subtract who has opted to not receive emails, each of the 20 or so pages of the membership list must be checked (tedious, but this takes about five minutes, versus trying to figure out how this info is stored in the bowels of the mailing list server).

Where the lines are defined by the number of carriage returns. The number of lines of every page in the wiki is in PageSize , which is exported to a text file and the second column is summed*. Note that the the PageSize of any moinmoin wiki shows the number of bytes of each page. To change it to the number of lines, the wiki engine (Python) is slightly modified.

edit Page.py . In the size() function, comment out the line

and add these two lines

* - To sum the columns, paste the PageSize page to a text file and use awk to sum.
