Do you mean the "warning" message from case.outputsgroup in w2web: warning: !!! Struct file is not consistent with space group found. sgroup found: !!! Struct file is not consistent with space group found. Number and name of space group: 62 (P n m a) I guess you could ignore it and proceed on, or the safer option should be to convert Pbnm to its Pnma form by clicking "Yes" to use the struct-file generated by sgroup.
