<div dir="ltr">hi Chimera users<div><br></div><div>We have determined a pseudo-atomic resolution cryoEM density of a helical co-polymer (two unique chains for the repeating hetero-dimer). We would like to compute map-versus-model FSC curves for each of the unique chains. We'd like to use the Zone tool to mask out the relevant density per chain within ~3A or so of the atoms in our atomic model, but we would like the edges of this mask to be appropriately "soft" (whereas right now zone masking appears to employ a hard edge). has anyone already solved this problem? </div><div><br></div><div><div><div dir="ltr">~Adam</div></div>
