<p>Hi Konstantinos,</p>
<p>The out of range projection index errors usually means the code
can't correctly read the binary datafile as you said. Judging from
the values in your cdf file, I think something went wrong during
your conversion. Expected types are float for the data, and
unsigned integers (4 bytes) for time & ids. I suggest trying
something like this in your program: </p>
<p> uint32_t id1, id2,** timeMS; float** data;</p>
<p> // recover data<br>
</p>
<p> for (id1=0; id1<bins_elts; id1++)<br>
{<br>
for (id2=0; id2<nCrystalsTot; id2++)<br>
{<br>
fwrite((char*)(&timeMS[id1][id2]) , sizeof(uint32_t),
1, pFile);<br>
fwrite((char*)(&data[id1][id2]) , sizeof(float), 1,
pFile);<br>
fwrite((char*)(&id1) , sizeof(uint32_t), 1, pFile);<br>
fwrite((char*)(&id2) , sizeof(uint32_t), 1, pFile);<br>
}<br>
}</p>
<p>Besides, I am not sure why your datafile header states 188811
events, while I would expect 107928 events from your numbers (nb
of projections * nb of pixels).</p>
<p>Best regards,</p>
<p>Thibaut</p>

<p>Dear users/developers,</p>
<p>I am trying to create a program that will write experimental
results to the appropriate .Cdf ascii format. I am using this
loop:</p>
<p> char buffer [20];<br>
sprintf(buffer, "CDF_CstrProj.Cdf");<br>
pFile = fopen (buffer, "w");<br>
for (id1=0; id1<bins_elts; id1++)<br>
{<br>
for (id2=0; id2<nCrystalsTot; id2++)<br>
{<br>
fprintf(pFile,"%6d ",timeMS[id1][id2]);<br>
fprintf(pFile,"%6d ",data[id1][id2]);<br>
fprintf(pFile,"%6d ",id1);<br>
fprintf(pFile,"%6d ",id2);<br>
}<br>
}</p>
<p>Where id1 is the projectionID (0-35) and id2 is the pixelID
(0-2997). Data are the counts. I am using integers in data but I
have also try it with floats. Then by using a .Cdh I try to
reconstruct. There is a problem there. Probably castor-recon
does not recognize the file correct, because I am getting this
fault repeatedly (the "Projection index" only change:</p>
<p>***** oIterativeAlgorithm::StepInnerLoopInsideSubsetLoop()
-> A problem occured while computing the projection line !<br>
***** iScannerSPECTConv::GetPositionsAndOrientations() ->
Projection index (538976288) out of range [0:35] !<br>
***** vProjector::Project() -> A problem occured while
getting positions and orientations from scanner !<br>
***** oProjectorManager::ComputeProjectionLine() -> A problem
occured while forward projecting an event !</p>
<p>I am attaching the file in order that you take a look and help
me.</p>
<p> </p>
<p>Thank you in advance,</p>
<p>Konstantinos</p>
