BML_CROP_IDX_VALID calculates valid sample indices for a time window and file coordinates Same as BML_CROP_IDX but bounds the starts and ends sample to the 1 and nSample if necesarry Use as [starts_idx,ends_idx] = bml_crop_idx_valid(cfg) [starts_idx,ends_idx] = bml_crop_idx_valid(cfg, starts, ends) [starts_idx,ends_idx] = bml_crop_idx_valid(cfg, starts, [], samples) [starts_idx,ends_idx] = bml_crop_idx_valid(cfg, [], ends, samples) where cfg is a configuration structure or roi table row cfg.starts cfg.ends (cfg.samples) cfg.t1 cfg.s1 cfg.t2 cfg.s2 cfg.nSamples - double: total number of samples in file cfg.tol - double: tolerance. Defaults to 1e-3/Fs. if starts and ends are given (3 argument call) the values of cfg are ignored
