[ncl-talk] Fwd: RIP4 Trajcalc

I know this isn't quite applicable to NCL but I know that there is a little
documentation on NCL's website about RIP and I wanted to try and see if
anyone in the group could assist me.

I am trying to run RIP4 on Yellowstone and I believe that RIP should be
working, I was able to run ripdp for wrfarw. I have generated hourly files
(from 0 to 12 hours) from an idealized simulation that I would like to use
for a trajectory calculation but when I try to do the calculation I get an
error about a segmentation fault.

I ran ripdp using this line:

ripdp_wrfarw Sierra_Test basic
/glade/scratch/lwheeler/em_hill2d_x/wrfout_B-2_2-4km-01-01_00:00:00


Everything worked and so I proceeded to run the trajcalc using:

rip Sierra_Test trajcalc.in

Which contains:

&userin
 idotitle=1,titlecolor='def.foreground',
 tacc=120,timezone=-7,iusdaylightrule=1,
 iinittime=1,ifcsttime=1,ivalidtime=1,inearesth=0,
 flmin=.09, frmax=.92, fbmin=.10, ftmax=.85,
 ntextq=0,ntextcd=0,fcoffset=0.0,idotser=0,
 idescriptive=1,icgmsplit=0,maxfld=10,itrajcalc=1,imakev5d=0,
 ncarg_type="cgm"
 /
 &trajcalc
 rtim=4,ctim=12,dtfile=3600.,dttraj=600.,vctraj='z',
 xjtraj= 80, 100, 120, 140, 160,
 yitraj= 0, 0, 0, 0, 0,
 zktraj= 565.4935, 565.4935,565.4935 565.4935,565.4935,
 ihydrometeor=0
 /


>From the documentation I found that when itrajcalc=1 that everything else
in &userin is/should be ignored. When I run rip though I get the following
error:

 Welcome to your friendly RIP (V4.6.6) output file !

Am I missing any links to pertinent parts of the RIP code? I copied the
precompiled directory into my home dir under bin/RIP4/.

setenv PATH $PATH\:$HOME/bin/RIP4/
setenv RIP_ROOT /glade/u/home/lwheeler/bin/RIP4/
setenv NCARG_ROOT /glade/u/apps/opt/ncl/6.1.0/gnu/4.4.6


Some online documentation that I found suggested that my times were
incorrect but I don't think that's the case and I've tried making
adjustments and I continue to get the same errors. Any help or suggestions
would be appreciated.

Thanks,
Lauren Wheeler
