[gradsusr] Ensemble mean & Anomaly

[Chorley Weather]

Hi all, 

I have a couple of questions, firstly I am trying get the mean run in a
spaghetti graph of the GEFS but I seem to keep getting the control run.
Here is the script: 

'set t 1 65'
'set e 1'
'set csmooth on'
'set cmark 0'
'set lat 53';'set lon -2.23'
'set vrange -30 30'
'define t850=tmpprs(lev=850)-273.16'
'define ensmean=ave(t850,e=1,e=21)'
'set gxout line'
'set ccolor 2'
'set cthick 8'
'd ensmean' 

Second question, using the GFS how do I produce anomaly charts with this
script, im not sure how to define it..... 

'set t 'i
'set grads off'
'set csmooth on'
'define geopotdam = hgtprs(lev=500)/10'
'color -gxout shaded -30 30 1 -kind blue->white->red-> -xcbar 10.1 10.3
0.7 7.74 -fs 10'
