Greetings everyone!
Trying to calculate dose, error appears.
ERROR: No image data in nput volume #0
What is volume #0?
Thank you!
The error message means that the dose volume for the beam was not calculated.
Probably this is because there was an error when running Dosxyznrc. Could you upload the log file? It should contain more info that describes the what went wrong.

I have seen the same error recently, when the lab where it was originally developed picked up the project again, and the person who started working on it asked me. I developed the Slicer part of this dose engine, but unfortunately I don’t have the capacity to work on it anymore. I will tell the medical physics student about this forum topic, maybe you could team up.
The Dosxyznrc output doesn’t seem to be complete in the log.
If the executable was found, the log should contain something like this:
b"================================================================================
EGSnrc version 4 for win3264 Tue Jun 2 15:17:15 2020
================================================================================
I helped the student that @cpinter mentioned fix their issue, so maybe the same problem is happening here.
The Orthovoltage dose engine is harded-coded to use AIR512ICRU and WATER512ICRU mediums. If you are using the 521icru.pegs4dat or 700icru.pegs4dat that comes with EGSnrc, then the dose calculation will fail. You could test this by changing/adding the air and water values in the pegs4dat file to AIR512ICRU and WATER512ICRU, or by using a pegs4dat file that has them already defined.
Thank you a lot! But how can I fix these pegs4dat icru files or find correct icru file?
This is not a permanent solution, just trying to determine if this is what’s causing the problem.
If you open the pegs4dat file that you specified in the orthovoltage config, look for the AIR medium (search for MEDIUM=AIR), and replace both MEDIUM and STERNCID values with AIR512ICRU.
As Kyle said, EGSnrc comes with pegs data that use high energy cut offs (ECUT and PCUT) that do not work for lower energies such as that of orthovoltage. So you need to create your pegs based on the materials of your simulation and photon energies. Refer to egs manual pirs 701 on how to create pegs.
Hi, I have this problem too, I just can’t seem to get the Orthovoltage system working. Here is my first error in log
“ctcreate output (last paragraph):
Input the x,y,z dimensions (cm) of the dosxyznrc voxelson one line

Dimensions in at least one direction < min allowed. Either increase
dimension(s) or go into dosxyznrc_user_macros.mortran and increase IMAX,
JMAX and/or KMAX”
I have changed these numbers as suggested by little endian but it never seems to register the change. Do I have to recompile the ctcreate data files?I tried that and was given an error, 1d etc etc… 
haha, if anyone can offer suggestions that be be fantastic.
