I have a ct dicom image of a phantom and I want to dosimetry with dosxyznc code , for this purpose i gave the specification of my phantom and when enter it in the ct create code i have met this error
Working on file :
Error opening file .
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

thanks in advance to your attention or maybe your answer.
Hello Milad,
Without your input file it is next to impossible to give exact answer to your question but I will try to give at least some help.
I myself encountered this problem several times and it did not have anything to do with program itself (except for not too good error reporting). Always it was problem with syntax of input file, with such things as empty line in middle of geometry definition, two empty lines as separator between cells and surfaces, or invalid number of parameters for some function I have been using for first time for example.
I tried as first step to go slowly through input and double checked everything in it. As it usually did not help (I an only human, you know), the next step was to "cripple" my input file and deleted parts and/or simplified it. That mean for example delete 15 of 16 surfaces and cells. Yes, it totally destroyed the geometry and/or physics, but as soon as the error changed I stepped back (undoing that deletion) and examined those line carefully and usually finding something like wrong sign or cell defined with old surface number etc.
I know this is not an easy way, but I could not think of anything easier (except for rewriting from scratch, but I am not sure if it is easier through :-) ). If you found an simpler solution, I would not mind If you share it ;-).
Also check the name of your file for typos, and folder in which you are running it if it actually contains this file, as the first two lines ("Working on file : " and "Error opening file .") are somewhat free from any filenames/paths despite from what spaces suggest.
Hope this helps,
Michal
hello Dr Hadad
thank you so much for your answer.
now I can read my ct dicom image with ctcreate code with moving dicom image into another drive of my pc. previously my dicom image was in the desktop.
