-We want to investigate the fragmentation reactions of 2-pentanone in an EI-MS experiment. Therefore, we provide the lowest conformer found by `CREST` at charge +1 as input <2-pentanone.xyz>. We only want to get unique fragments so we use the -msmolbar flag to sort out duplicates with `molbar`.  Before starting crest, we should make sure that `molbar` is properly installed and can be executed globally.
