Do you really want to read the whole of a long reflection loop into memory rather than parsing it one line at a time (which should be possible once you have worked out what is in the file)? That would end up with storing the reflection list twice, the memory copy of the input file and the

Hi Oliver a few years ago I used the ccp4 FFFEAR program from Kevin Cowtan for this sort of domain search. It was very good but also quite labour-intensive. I have not followed up since to see if it was updated or the functionality was included in Buccaneer. cheers Martyn

Completely agree. Perhaps there could be a distinction between working and deposition formats. They are for different purposes and, therefore, could differ from each other -- Eugene On 19 Sep 2013, at 10:45, Phil Evans wrote: Do you really want to read the whole of a long reflection loop into

Hi Peter, Thanks for posting the startools, I think many developers can benefit from these. [snip] One final point on this: line-by-line processing needs to allow for the fact that there is no requirement at the format specification level for reflection data to be one reflection per

There's definitely a case for working formats, but as we think about improved working binary formats following on from MTZ (maybe based on HDF5 containers), particularly for unmerged data (for example in the DIALS project), it makes sense to use [mm]/[image]/cif definitions where appropriate,

I doubt that memory mapping will help the problem in any way. At best, it will translate lack of RAM into overhead of data exchange between disk and RAM, although seamlessly for programmer. However, modern OSes do this anyway for excessive heap allocations. Phil's comment was specifically about

Inevitably, there is a trade-off between generality and efficiency. Nothing is offered for free, and containers do mean a price tag for complexity and performance (and sometimes maintenance and support) as well. What happens, one always considers all this against development cost, which is
