[ccp4bb] on building a helix fragment by coot

[Smith Liu]

Dear All,
 
If I need to build a fragment of helix to a fragment of density by coot, should 
I use baton build method or should I use place Helix here function? I have 
tried both, but I find it is difficult to place the sidechains to the map 
mosition which looks like where shold be occupied by the sidechains.
 
I am looking forward to getting your message on how to correctly buld the helix.
 
Best regards.
 
Smith
