[CP2K:2545] Constraint warning with AMBER PDB file

[Laino Teodoro]

Dear Lepka,

unfortunately AMBER topology files do not have any information about  
molecule names. What is stored there is the residue name, which we  
don't really use within CP2K.

As you realized CP2K is assigning new molname: MOL01..
You can either specify the whole list within the appropriate molname  
keyword or alternatively just use the other keyword MOLECULE in this  
way:

MOLECULE 1..15

I have no clue if you really have 15 molecules in your input or just 2.
This should fix your problem.
Teo

p.s.: just a comment: please upload 1 unique tar (gzipped) file: this  
makes life easier.
