Load acquired sequence files (P1/90, P1/11, raw P2/94 or raw P2/11) to extract per-shotpoint attributes and graph them against SP. P2/94 adds streamer depths, pitch/roll/heave, gyro/network observations and GPS heights; P2/11 adds gun depths/pressures/timing, MRU, gyros and GPS heights (auto-grouped by node). Files are processed locally — nothing is uploaded.

Builds CMP fold maps from P1 files containing shot (S) and receiver group (R) records. Each shot–channel midpoint is binned on the grid below, split into offset quarters of the cable (nears / near-mids / far-mids / fars / alls). Fold accumulates across every file you add — load the next sequence to build up coverage. Files are processed locally.

Priority (1–100): sets the acquisition order — lower numbers are acquired first, higher numbers last. 50 = Neutral (default). E.g. a line set to 1 is shot before all others; a line set to 100 is left until the end. Within the same priority the planner still optimises transit time.
