Dear MODELLER,

In order to generate hundreds of PDBs, I submit multiple jobs to the cluster. The input template is the same for all the jobs. For each job (i.e. each batch), 10 PDBs are generated. The 10 PDBs within the same batch are different in their "Objective Function" in the PDB remark. But the PDBs between the batches have the same "Objective Function".

For example,  ) the 3rd PDB in Batch 1 has the same "Objective Function" as the 3rd PDB in Batch 5 ) the 6th PDB in Batch 2 has the same "Objective Function" as the 6th PDB in Batch 10

So it seems that all the jobs are started from a same "seed". Is there a way to randomise the seed?

Thank you!

Cheng

The script I use is:

log.verbose()
