gastropy.assess_quality(n_cycles, cycle_sd, prop_normo)[source]#

Assess EGG recording quality based on standard criteria.

Quality control thresholds are based on EGG literature conventions: sufficient cycles (>=10), stable rhythm (SD < 6s), and normogastric dominance (>=70% of cycles in 2-4 cpm range).

Parameters:

  • n_cycles (int) – Number of detected gastric cycles.

  • cycle_sd (float) – Standard deviation of cycle durations in seconds.

  • prop_normo (float) – Proportion of cycles in the normogastric range (0 to 1).

Returns:

Dictionary with boolean quality flags:

  • sufficient_cycles : At least 10 cycles detected.

  • stable_rhythm : Cycle duration SD < 6 seconds.

  • normogastric_dominant : >= 70% normogastric cycles.

  • overall : Sufficient cycles AND (stable OR normogastric).

Return type:
