<div dir="ltr">Thank you so much! Is 'Create maximum entropy map'
in the latest nightly build that could create the omit map you
guys suggested? I was trying to run it but got the error message
'No column labels specified'. In the columns labels it shows
'---' and don't give me any option to change... I just loaded my
mtz file and the ligand-free pdb file and left all other
settings as default. Thank you so much! <br>
