Apologies, this was a bug introduced by a recent change. 
It is fixed and will be in 6.1.2

Subject: [ccp4bb] TLSANL gives zero off-diagonal ANISOU matrix in CCP4 6.1
 
Dear all,

I have observed a strange behavior when using TLSANL (v. 3.8) under CCP4 
6.1.0 : using identical input (only coordinates have changed a bit after 
some TLS+restrained refinement) what used to work perfectly well before 
(under CCP4 6.0), now gives an evidently wrong calculation, resulting in 
writing final ANISOU matrices with U(1,2), U(2,3) and U(1,3) equal to 
zero. Otherwise the program does run and finishes properly without 
explicit errors or warnings.

the input is simple :
ANISO
BINPUT t
BRESID t
ISOOUT FULL
END

(seeking to end up with a B-factor column ont the ATOM cards containing 
the isotropic equivalent of the TOTAL ADP (including TLS); this 
generates ANISOU cards describing the TLS modelization for each atom 
included in TLS domains;
although I am aware that this is still matter of debate, this 'seems' to 
be the most correct way to communicate what has been done, otherwise 
REFMAC5 will just leave the residual B fac on the ATOM card, giving 
somewhat 'misleading', frequently extremely low values)

Any help on this TLSANL problem will be very much appreciated!

Best,
