Hello,
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.

HARK SupportMay 27, 2019 at 4:59 pm #837Earlier 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.

May 27, 2019 at 5:12 pm #841One 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 #842Okay, I have found my mistake, I had kept the condition as an output so the network was not working.
Thank You for your help
