@danieldeidda test_DataSymmetriesForBins_PET_CartesianGrid failed. Possibly we made a mistake in the merge, or there is something else.

danieldeidda · 2024-01-16T14:56:18Z

something is happening with the segmentIndices::_timing_pos whcich occasionally is different. Need to go deeper in debugging though

I guess the problem is happening in one of these modifications

Actually not sure anymore because the test is giving errors when the 2 bins are actually the same. also it happens for a non-tof test

can you paste some sample errors, for both TOF and non-TOF?

test failure in OSMAPOSL_parallelproj is weird as non-TOF, but occurs in all Release builds (and isn't run in the Debug jobs), so not a one-off.

test_proj_data_info failures:

printing of bins is also flawed (replace as in other file) so we can't see what's going on
Debug runs have assert error https://github.com/UCL/STIR/actions/runs/7614648272/job/20737408998?pr=1334#step:10:921
worrying is Error. malloc(): corrupted top size https://github.com/UCL/STIR/actions/runs/7614648272/job/20737408026?pr=1334#step:10:1110

+    this->max_num_central_timing_poss_to_process =
+      this->proj_data_sptr->get_max_tof_pos_num();


I think is wrong, it probably needs a divide by 2 or so

mh not sure than the shift is different then zero if we want to use them all

in fact, we don't support this yet, but having wrong code is a bad idea. Add a comment and throw an error if the argument isn't what we expect?

However, it seems hard to know what the argument should be. For 2 TOF bins, the max number of central should be 1. For 3 TOF bins, it should also be 1.5... (1 could work, but how would one say then we only want to do the central one). Looks like the name is still wrong.

Or remove...

I've merged master to resolve conflict. Sadly, the MacOS build now fails because it requires C++-14 (due to upgraded boost version). https://github.com/UCL/STIR/actions/runs/7677624387/job/20926592594?pr=1334#step:9:1146

@danieldeidda I'd really like to release STIR 6.0.0 soon. We can easily postpone this to 6.1. Let me know.

danieldeidda · 2024-02-02T11:28:14Z

Hi I have been looking at it but haven't been able to find the source of the error. Let's postpone to 6.1 then

this seems to have fixed the problem. Let's see how the test goes

src/recon_buildblock/PoissonLogLikelihoodWithLinearModelForMeanAndProjData.cxx

KrisThielemans · 2024-03-25T15:34:01Z

We will still have to think about consequences for IO. In particular, Siemens TOF order needed to be handled, so this code will have to be adapted

STIR/src/IO/stir_ecat_common.cxx

Lines 208 to 212 in 8ced2d7

    
           for (int timing_pos_num = 1; timing_pos_num <= max_timing_pos_num; ++timing_pos_num) 
        
             { 
        
               timing_pos_sequence[2 * timing_pos_num - 1] = timing_pos_num; 
        
               timing_pos_sequence[2 * timing_pos_num] = -timing_pos_num; 
        
             }

KrisThielemans · 2024-03-25T15:46:26Z

Should put a check in

STIR/src/buildblock/ProjDataFromStream.cxx

Lines 152 to 155 in 8ced2d7

    
           ProjDataFromStream::set_timing_poss_sequence_in_stream(const std::vector<int>& seq) 
        
           { 
        
             this->timing_poss_sequence = seq; 
        
           }

that values in the seq array are between min and max, to catch people using the "old" convention. (projdatainfo)

KrisThielemans · 2024-03-25T15:58:56Z

#1389 introduced the capability to read TOF bin order from the Interfile header:

STIR/src/IO/InterfileHeader.cxx

Line 621 in 8ced2d7

add_key("TOF bin order", &timing_poss_sequence);

. However, the value of that keyword would now be different.
(Note that #1389 was after the 6.0.0 release, so we are not breaking backwards compatibility w.r.t. a released version).

@NicoleJurjew I don't think this will affect you (as it's independent of the parsing of the Siemens Interfile header), but let us know if it does.

actually, this should be deleted, and the whole change w.r.t. master reverted
