Error using Fox no-gui: with flipping option

[mpingus]

Hi, I am testing the no gui version with the examples provided. However, when changing some parameters, such as the enable flipping option, this error message comes up.
I opened the cimetidine-powder.xml in the fox gui version 2024 and toggled the enable flipping option (yes and no). I saved both versions and tried to optimise them using the terminal.

This is the part in the xml file:

  <Option Name="Flexibility Model" Choice="0" ChoiceName="Automatic from Restraints, relaxed - RECOMMENDED"/>
  <Option Name="Enable Flipping" Choice="1" ChoiceName="No"/>
  <Option Name="Auto Optimize Starting Conformation" Choice="1" ChoiceName="No"/>
  <Option Name="Optimize Orientation" Choice="0" ChoiceName="Yes"/>
  <Option Name="Rotation Center" Choice="0" ChoiceName="Geometrical center (recommended)"/>

This is the error I am getting:
ObjRegistry::Find(Enable Flipping): Not found !!
:4 object registered:
0(Flexibility Model)
1(Auto Optimize Starting Conformation)
2(Optimize Orientation)
3(Rotation Center)
LibCryst ++ exception thrown!!
Message: ObjRegistry::Find(Enable Flipping): Not found !!

Thanks for the help!

Could you attach the modified xml file ?

cimetidine-noflip.xml

I have no problem running it with just Fox --nogui Downloads/cimetidine-noflip.xml, or Fox-nogui Downloads/cimetidine-noflip.xml

I installed fox on linux using the precompiled package objcryst-fox. Could this be an older version that perhaps does not support this parameter option?

Thank you for your help

That code is 10 years old, so I doubt that. I would still try to recompile from source though.
