Re: [ESPResSo-users] particle does not exist

[Stefan Kesselheim]

Dear Xikai,
please check the content of confout for particle 4633. There must be a section 
like
Are you sure that there is something like { particle 4633 pos 1 2 3 } in there?
Just after reading the configuration you should then be able to e.g. print its 
position, 
puts [ part 4633 print pos ]
and also to delete it. It is very likely that this is a simple error in your 
particle indexing or something similar. 
Cheers and good luck
Stefan
