[buster-discuss] Buster can't get cell from mtz?

[Andrew Sharff]

Dear Sabine,


Thank you for sending the mtz file so promptly.

I am, however, unable to find any issue with this mtz file, either using 
CCP4 utilities directly or running mtzchk.

Please can you also send me the file mtzchk.2.log, referred to in the 
error message you attached in your initial email.

Can you also please confirm that the mtz file (data.mtz) that you sent 
me is indeed the same file that you have run BUSTER on. I ask this 
because in your initial email, the attatched program output you include 
suggests that that the cell dimensions of the data are

69.4650  124.6470  153.8770   90.0000   90.0000 90.0000

However, the cell dimensions of the mtz file you have sent me are

63.4650  104.6470  113.8770   90.0000   90.0000   90.0000


Regards

Andrew Sharff
