I ran 2D classification using cisTEM. I wanted to proceed to 3D classification using the particles of good classes. It took a while it it loads the particles in Refine Package tab and as soon as it was completed the GUI was abortet showing this errors in terminal:
int Database::ExecuteSQL(const char *)
And if I reboot the GUI, it doesn't allow me to open the 2D classification project.
How can I recover my project, or save particles from 2D classification for furthure steps?
