Simulink SDI interface error (safeTransaction)

Hi,

I am in trouble with the SDI interface : I aborted Matlab while it was saving a SDI session because it was not responding/slow.

I restarted Matlab and started a simulation with streaming enabled (I checked model configuration and streaming logo over my signals). At the end of the simulation I started the SDI interface which was empty...

I got the following error :

Error using Simulink.sdi.Engine/safeTransaction An internal error has occurred. Restart MATLAB before proceeding. If this problem persists, please contact MathWorks.

Error in Simulink.sdi.models.ImportDialog/updateRepository

Error in Simulink.sdi.controllers.ImportDialog/transferScreenToData

Error in Simulink.sdi.controllers.ImportDialog/cb_OKButton

Error in Simulink.sdi.controllers.ImportDialog>@(arg)cb_OKButton(this,arg)

Error in Simulink.sdi.controllers.Dispatcher/cb_OnNewMessage

Error in Simulink.sdi.controllers.Dispatcher>@(arg)cb_OnNewMessage(this,arg)

Error in message.internal.executeCallback

I restarted again Matlab and launched directly the SDI interface. I tried to load some runs which I previously saved but I am still getting this error.

I am working with Matlab R2015b.

Thanks for your help,

Benjamin

Problem solved by MathWorks support, workaround was :

_ 1. Run the following command in MATLAB:

>> tempdir

>> Simulink.sdi.getSource

2. Using Windows Explorer, navigate to the tempdir path listed in the result from Step 1

3. Close all instances of MATLAB. In the Windows Explorer window from Step 2, sort files by "Type"

4. Delete all files with the type "DMR"

5. Delete the file returned by the "Simulink.sdi.getSource" function if it was not deleted in Step 4

6. Reopen MATLAB and the Simulation Data Inspector. All Prior Session Data should be removed._

I had also a issue with a crashing Matlab/Simulink because of prior data in my Simulation Data Inspector which I was not able to remove from Matlab. Also not with the following command.

 Simulink.sdi.clear

But deleting all my DMR-files from my temp direction did work.

Thanks!

Benjamin Alvarez thanks for posting solution here.

I had same problem. It was solved with the steps you mentioned.
