I always see the quality of map decays after auto-refinement from ab-initio 3D model. Please check the attached file. During the creation of refinement package I gave 3 for number of classes (for 3D ref). While starting autorefinement, under starting reference, I see three volulems all with same name as 'Volume From Startup #1 - class#2'. But, under the directory of Assets/Volumes/ I see, startup_volume_1_1.mrc, startup_volume_1_2.mrc, startup_volume_1_3.mrc
Could you please explain the 3 volumes with same name shown under starting reference?
Please also advise how I can improve the map quality after autorefinement. I have done map sharpening, but it did not help.
Thanks for your time,
