Updating to latest version of EGSnrc on Windows 7. Running

Updating to latest version of EGSnrc on Windows 7. Running

EGSnrc-configure-windows.exe

seemed to go fine, but when I try to compile tutor1 using egs_gui I get the following error:

Failed to execute: makeEGS_CONFIG=C:programsegsnrcHEN_HOUSEspecsgnu_win32.conf EGS_HOME=C:programsegsnrcegshome!!!

The conf file exists at that location and the EGS_HOME directory exists. Can anyone help?

Dear all

Dear all,

when running tutor7pp using an IAEAphsp-source (generated by egs_brachy) the total energy in each region was calculated as expected but the pulse height distribution results came out ‘0’ for every energy with ‘-nan’ for the heights and errors in each region. Dose scoring via an additional ausgab object works however. Please see the attached screenshots of the output file.

If it’s any help:

a) The input file leads to the expected pulse height distributions when using an egs radionuclide source or monoenergies.

b) I tried solving the issue by changing the .conf files for the compiler according to https://github.com/nrc-cnrc/EGSnrc/issues/174 but that did not help either unfortunately, even when trying on two different CPUs.

Do you have any ideas what could be done to have the tutor7pp code calculate pulse height distributions when the source is defined using an IAEAphsp file?

Thanks đŸ™‚

The 2019 edition of the Monte Carlo Techniques for Medical Applications (MCMA) conference will be held in Montréal next June, jointly with ICCR this year. In my humble opinion, MCMA continues to be one of the, if not the most relevant conference in the field. Abstract submission deadline is now February 15.

Hello everyone

Hello everyone,

I am simulationg measurements of the TG-43 parameters of a HDR brachy source in a spherical water phantom (40 cm radius) in EGS_chamber. I score the dose in a 0.05 cm x 0.05 cm x 0.05 voxel. I surround the voxel with a sphere (always made of water) in which I use XCSE (enhancement = 528). I use a 50 MeV electron cutoff (kerma approximation). The problem is that my simulations are not so efficient (4 days to achieve 0.1% uncertainty). Are there other techniques to improve the efficiency? Thank you very much!
