Hi all,

I’m beginner of CASToR. I installed CASToR in virtual machine (ubuntu 18.04.2) and compiled CASToR using the provided Makefile.  
After that, I tried to reconstruct example (castor\_benchmark\_v3\_pet\_list-mode)  
I got the following error

[354] 09:23 vgate:~/Desktop/castor\_benchmark\_v3\_pet\_list-mode \> ./run\_benchmark\_pet\_list-mode\_unix.sh

Dear Suguru,

If you still encounter the issue:  
It looks like the software couldn’t find the directory containing the CASToR configuration file, in particular the geometry file. Using the Makefile, the environnement variable CASTOR\_CONFIG must be sent to the config directory before running the benchmark. The location looks like to be home/gate/castor\_v3.0.1/config/ in your case.

Hope this helps,  
Thibaut
