[ccp4bb] Some advices on model modification

[allen price]

Dear all:
I got a dataset at 2.8 angstron. I have tried several ways such as phaser, 
MRBUMP,BALBES,but still can't solve the 
data,which means I have to edit my model. Maybe I'd better cut it off or delete 
the water or loop. I really have no 
idea,as it is my first time to do such things, I alway used the whole model to 
mr. Could anyone give me some advice? 
what kind  of software do you guys use? really need you help!
Best regards,
Allen
