Checking field maps in each session

[sinhaharsh]

In our projects, we acquire two field maps in each session, one in the Anterior-Posterior (AP) direction and the other in the Posterior-Anterior (PA) direction. Currently, there is no mechanism to confirm whether both field maps were acquired in each session and whether they have opposite PED.

• Add a session-level validation step to verify the acquisition of both field maps for each session.
• Develop a mechanism to check the consistency of PED in the acquired field maps.
