HARK FORUM › Node list not showing up in hark
May 27, 2019 at 2:56 pm #834
Myself Rohan Sheelvant, I am using HARK (hark_designer) software for a research project at NUS. I have followed the instruction given on the website https://www2.hark.jp/wiki.cgi?page=HARK+Installation+Instructions and https://www.hark.jp/install/linux/ to install the HARK system on Linux system.
The problem I am facing now after installation is that after running the hark software (hark_designer), no nodes are showing up on the node list. I have attached the SS for your reference.
Can you please let me know if I am missing any step in the installation or if I need to do any additional procedure for the same.
Thank you for your help and time.

Thank you for your inquiry.
Have you tried adding the nodes in the preferences ?
If not, please follow the steps below:
1. Click Preferences
2. Click Packages
3. Select the node references that you need from the list

Earlier it did not have any packages, however, I just now checked again and it worked.
I am now trying to record sound using HARK by following these steps https://www.hark.jp/document/2.4.0/hark-cookbook-en/subsec-LearningHARK-001.html
and I am using this RASP device http://wiki.seeedstudio.com/ReSpeaker_Mic_Array_v2.0/ to record the audio.
I have created the network for recording using HARK also set the parameters accordingly(I want to record a sound at 16KHz for 5 seconds). After setting the parameters I clicked the button EXECUTE. After this, I check the FILE button in HARK_developer and I could find 4 audio files named sep_0,1,2,3 (.wav). However, on playing these files I hear audio of less than a second and only some noise in it.
[I have attached the relevant screenshots with this post]
Can you please tell me if have made any mistake while building the network?
I have checked my recording using audacity and all the mics are working fine.

One mistake I noticed, my MAIN_LOOP was on subnet. I have now changed it to iterator.
Now after clicking the EXECUTE button, I get the status as stopped, Does this mean some error in the network?May 27, 2019 at 5:37 pm #842
Okay, I have found my mistake, I had kept the condition as an output so the network was not working.
Thank You for your help
