I think Pointless 1.2.23 was a broken version which escaped to the
wild in CCP4 release 6.1.0. The more recent release 6.1.1 has a fixed
version, and some more recent versions are also available from our ftp
site
eg ftp://ftp.mrc-lmb.cam.ac.uk/pub/pre/pointless-1.3.2...
sorry about this

I'm hoping someone can help me with a pointless problem. I am
trying to reindex
data into an orientation that I used to solve the structure
initially. While
I can get pointless to give me the reindexing needed to make the new
data match
the old data for the project, when I ask it to write the data to
HKLOUT it does
not carry out the reindexing. I was under the impression from the
documentation
it would write out the reindexed solution. Am I doing something
wrong or have
I found a bug in my particular space group. I seem to recall getting
this to work
on a different project in the past. I have also tried a number of
different
versions of pointless, and all give me the same results. The output
file is shown below.
Thanks in advance for any help.

Operators labelled "exact" are exact by symmetry
For inexact options, deviations are from original cell
(root mean square deviation between base vectors)
Maximum accepted RMS deviation between test and reference cells
(TOLERANCE) = 2.0
[h,k,l] exact
[-h,-k,l] exact
