Open selection in Praat, Praat opens normally, but the windows of Praat are blank

ELAN
1

platform: windows11 x64;
ELAN Version: 6.9;
Praat Verson: 6.4.34

When I select the “open selection in Praat” option in ELAN, the Praat program starts normally, but both the Objects window and the Picture window are blank. No error messages are displayed during the entire process. I would be extremely grateful if anyone could offer some help.

Hello,

Apologies for the late response.
I downloaded the Praat Verson: 6.4.34, and tested it with ELAN 6.9 and I faced the same problem.

When I tried the older versions of Praat ( tried 6.3.09 ) , I am able to open the selection in Praat.
Something could have been changed in handling inter-process communication in Praat.
You can try the older versions of Praat and we will look into this issue with the latest version.
Before trying out the older versions, you can remove the praat.pfsx file from .elan_data folder. Then when you open the selection ELAN asks you to locate the Praat.exe file, you can point to the correct .exe file.
Thank you for reporting this.

Best,

Thank you very much for your reply. I tested this version of Praat on my computer, and it is working fine now. I really appreciate it.

Just wanted to chime in and say this is still an issue for Elan 7.0 and Praat 6.4.40.

Hello,

We revisited the issue and found that it appears to be specific to the Windows version of Praat. The Mac and Linux versions of Praat (tested version 6.4.40 on Mac) seem to work with ELAN.

It seems that the Windows version of Praat 6.4.25 functions correctly, but any version beyond this encounters issues. The ELAN integrated native “sendpraat” library is based on the sendpraat.c file. Upon a brief review of the current version, we did not immediately identify any changes that could account for the differing behavior.

Additionally, installing any version of Praat above 6.4.25 and using the pre-built sendpraat-win.exe with the command .\sendpraat-win.exe praat Quit (one of the examples provided when running sendpraat without arguments) does not terminate the running Praat application, unlike older versions( 6.4.25 ). This suggests a need to evaluate if scripting via sendpraat is functioning as intended on windows versions.

Could there be a need for modifications in the Praat code to restore this functionality? We kindly request that you report this to the Praat developers to see if they can assist us on this.

Best,
Divya

The problem has been solved in Praat 6.4.42. Thanks for bringing this to our attention.
