[Pw_forum] Is it necessary to clear outdir / wfcdir before calculation?
Thanks for your advices, I will remove the output if it is not necessary.

[Pw_forum] Is it necessary to clear outdir / wfcdir
In my calculation restart_mode="from_scratch" is always used. But I find if a calculation ends with error, it will give different errors depends on the whether the outdir is empty or not. So I wonder whether it affect the calculation results.

At least, there are three methods to avoid the effect of last calculation. restart_mode = 'from_scratch' or change prefix or rm -rf $TempDIR/* -- GAO Zhe CMC Lab, MSE, SNU, Seoul, S.Korea At 2011-09-08 13:41:38,WF wrote: Hello everyone, Recently I make a small bash script to run a lot of small pw.x calculation one by one.

Is it necessary to delete them before starting a new calculation ? Because I have done a lot of calculation, I would like to verify whether this will affect the results to determine whether I should modify the script to restart my calculation again, or just use these result.

If you do a "nscf" calculation you will need data produced in a previous "scf" run (irrespective of restart_mode), therefore you must specify the correct outdir and prefix. If you specify wrong values, of course that the results will be affected. In some cases the calculation will give an error message. Please sign your posts and provide your affiliation. Thanks.
