Problem running spm12 using R2019a on Centos 7

When I issue the spm command, it displays the startup window. After clicking on a button, I get:

(MATLAB:374189): GLib-GObject-WARNING **: 09:26:25.382: cannot register existing type 'GtkObject'

(MATLAB:374189): GLib-GObject-CRITICAL **: 09:26:25.382: g_type_register_static: assertion 'parent_type > 0' failed

(MATLAB:374189): GLib-GObject-CRITICAL **: 09:26:25.383: g_type_register_static: assertion 'parent_type > 0' failed

and then it freezes.

OS: Linux 3.10.0-957.el7.x86_64

Compiler: gcc 6.3.0

Glib: 2.42.2

Java: 1.8.0_211

Any ideas on what needs to be fixed?

Answer 1

[Kestas Subacius]

The error messages you provided indicates that this issue may be related to an internal type conversion between MATLAB data-types and the SPM12 data-types.

Since you can start the SPM12 application through MATLAB, and the freezing only occurs after the button press, this issue seems to originate in the SPM12 codebase.

My best suggestion would be to reach out to someone from SPM team for assistance in debugging and resolving this issue.

Looks like a library compatibility issue to me.

Hi All,

I had the same problem with Ubuntu 18.04 (gcc: 7.5.0, glibc: 2.27-3ubuntu1, java: 1.8.0_242).

I reached out to one of the developers about this and was told that the error is due to an issue with Java when displaying the welcome message in the graphics window. You can see the cause in the source code here: https://github.com/spm/spm12/blob/master/spm_browser.m#L54

To fix it, export the environment variable SPM_HTML_BROWSER as 0 before launching SPM12. In a terminal, this would be "export SPM_HTML_BROWSER=0"

This worked for me, and I hope it works for others as well.

This worked for me! I am now able to use the GUI and load images just fine. Thanks!

Worked for me too. THANKS A LOT!
