Reference tracking using NDI Polaris Vega ST returns global coordinates about pluslib HOT 12 OPEN

Hi! Thanks for the tip, will try your suggestion! The transforms are not send to the MHA file, correct? Do you know how I can send these transform to this output file? I tried adding the transforms in the ‘PlusOpenIGTLinkServer’ tag but didn’t see them in the MHA that’s why I ask. The only warning I could find for now is the ‘ReferenceToReference’ is not defined but this did not seem like a big problem to me? Cheers!

My log file gives me this (after changing the ToolReferenceFrame to Tracker): |DEBUG|1101.454000| Application configuration file 'P:/PlusApp-2.8.0.20191105-Win64/bin/PlusConfig.xml' saved| in P:\workspace2\PlusLib\src\PlusCommon\vtkPlusConfig.cxx(536) |DEBUG|1101.471000| Device set configuration is read from file: C:\Users\s137228\Documents\OneDrive - TU Eindhoven\Config files\MEDUSA_test7.xml| in P:\workspace2\PlusLib\src\PlusCommon\vtkPlusConfig.cxx(249) |DEBUG|1101.473000| Device set configuration file contents: | in P:\workspace2\PlusLib\src\PlusCommon\vtkPlusConfig.cxx(252) |INFO|1101.476000| Connect to devices| in P:\workspace2\PlusApp\fCal\Toolboxes\QConfigurationToolbox.cxx(158) |DEBUG|1101.514000| StartupDelaySec: 1.000000| in P:\workspace2\PlusLib\src\PlusDataCollection\vtkPlusDataCollector.cxx(108) |DEBUG|1101.516000| AveragedItemsForFiltering is not defined in source element "GeometryToTracker".

I tried multiple places within the config file but no luck yet. Furthermore, it shows that it will compute the GeometryToTRacker and ReferenceToTracker but why not the desired GeometryToReference?

Thank you, I will change it to info! Regarding the ‘GeometryToReference’, My .MHA file only returns “GeometryToTracker” and “ReferenceToTracker”, where can I add a tag in the config XML to also have my “GeometryToReference” returned? I am also fine with just the latter being returned and not having the global coordinates. I really need those relative positions for my tracking pipeline!

I would reduce your log level to INFO to make it easier to read and to filter out the unimportant entries. I don't see where it says it won't compute GeometryToReference — Reply to this email directly, view it on GitHub<#1111 (comment)>, or unsubscribe<https://github.com/notifications/unsubscribe-auth/ALTZ2VFRB6SCXR65JAJPHFLX2G5CDANCNFSM6AAAAAA4UQMEBI>.

I have put the desired Transforms in the TransformNames tag as you can see here: <PlusOpenIGTLinkServer MaxNumberOfIgtlMessagesToSend="1" MaxTimeSpentWithProcessingMs="50" ListeningPort="18944" SendValidTransformsOnly="TRUE" OutputChannelId="TrackerStream" > <DefaultClientInfo> <MessageTypes> <Message Type="TRANSFORM" /> </MessageTypes> <TransformNames> <Transform Name="GeometryToReference" /> <Transform Name="GeometryToTracker" /> <Transform Name="ReferenceToTracker" /> </TransformNames> </DefaultClientInfo> </PlusOpenIGTLinkServer> But when I press Record in the Capturing tab of fCal, the recorded .MHA file (the output file generated by recording) only contains GeometryToTracker and ReferenceToTracker. What am I doing wrong?

No, not on this part at least. I got some rendering warnings/errors but that is because I am not trying to render anything and did not include that in the config file. I only want the GeometryToReference to appear in my capturing output. I have been looking at the file format here: http://perk-software.cs.queensu.ca/plus/doc/nightly/user/FileSequenceFile.html But haven't found what I have been looking for... Is there no transform that I can id in the device or somewhere to get this transformation to appear in my MHA (sequence output) file?

Sorry for not closing this thread earlier, but I have found the solution by using this: http://perk-software.cs.queensu.ca/plus/doc/nightly/user/ApplicationEditSequenceFile.html I will close the thread now!
