[Chimera-users] .sld (MOLCAD, Sybyl 8.0) file import or visualisation of an inner surface (of a protein) in Chimera

Hi, My interest is a 4 helix protein which has a cavity inside. A colleague generated with a 1,4 Angström probe this “inner surface” with Sybyl for me and exported the surface as .sld file. Can I import this file into chimera somehow? Alternatively, can I generate such a surface with chimera? My knowledge of protein visualization is limited and I am very thankful for any help Thank you very much in advance. Best Wishes Natalie
