How do I create and render a custom region? How do I create and render a custom region in Drupal 7, when the Display Suite module is used?
I am not able to show/display a block into a custom region and  confused with the files structure. Please suggest any solution.
I got the solution and so sharing with all, if it could help someone:

Creating a custom region in our theme if we are using display suite module is slightly different.

1.First define region in your theme's .info file (same as we do without display suite)

regions[name_of_region] = 'Name of Region' 


2.Then print the following line in your template file wherever you want to display

print render(block_get_blocks_by_region('name_of_region'));
