Problem starting the Matlab GUI v 0.4.3

[mohamedamjad]

When I tried to open the GUI I got:

Error using exist
The first input to exist must be a string scalar or character vector.

Error in goGUIclass/updateLEDstate (line 2168)

with the actual version in branch master I got this error:

Error using Go_State.getInstance (line 135)
Invalid default value for property 'cur_settings' in class 'Go_State':
Invalid default value for property 'UI_P_SRATE' in class 'Main_Settings':
The class goGUIclass has no Constant property or Static method named 'UI_P_SRATE'.

Error in Go_State.getCurrentSettings (line 154)
                this = Go_State.getInstance();

Error in Core (line 61)
            this.state = Go_State.getCurrentSettings();

Error in Core.getInstance (line 71)
                this = Core();

Error in goGPS (line 67)
core = Core.getInstance();

Is there a working version of gogps? If yes, how can I download it

The error you are receiving is probably caused by some variables or state that are coming from another branch of goGPS. Try running the script "clearBranch" before relaunching goGPS and it should work! Let me know if this solved your problem!

[mohamedamjad]

Thank you ! The 0.4.3 version on go-project.org does not have the clearBranch script. I just re-pulled from the master branch and it works now! Before I re-pulled, I had the message bellow:

Error using Go_State.getInstance (line 135)
Invalid default value for property 'cur_settings' in class 'Go_State':
Invalid default value for property 'UI_P_SRATE' in class 'Main_Settings':
The class goGUIclass has no Constant property or Static method named 'UI_P_SRATE'.

Error in Go_State.getCurrentSettings (line 154)
                this = Go_State.getInstance();

Error in Core (line 61)
            this.state = Go_State.getCurrentSettings();

Error in Core.getInstance (line 71)
                this = Core();

Error in goGPS (line 67)
core = Core.getInstance();

It does: https://github.com/goGPS-Project/goGPS_MATLAB/blob/master/goGPS/utility/clearBranch.m

It just performs a cleaning of all the singleton classes, typically needed when switching branch. Restarting MATLAB has the same effect. Sometimes is useful to delete the last_settings.ini file!

Anyhow, I'm happy that you manage to run it: I'm closing the issue.

[mohamedamjad]

I think that there is no clearBranch file in the version 0.4.3 available on the website gogps-project.org. I confirm that it is available from the master branch of the Github.

Anyway, thank you for your reactiveness that was very helpful.

[clicat]

You are right the version from gogps-project.org is older than the one in the master branch, we will try to fix this in the near future. Thanks

Please helpme running goGPS.....it is failing with the above errors. I tried using clearBranch.m too. But no use
