Tutorial 5: Changing Dtype With neurocaps.analysis.change_dtype

Changes the dtype of all participant's numpy arrays to assist with memory usage.

import numpy as np
from neurocaps.analysis import change_dtype

subject_timeseries = {str(x) : {f"run-{y}": np.random.rand(50, 100) for y in range(1, 3)} for x in range(1, 3)}
converted_subject_timeseries = change_dtype(subject_timeseries_list=[subject_timeseries],
                                            dtype=np.float32)
for subj_id in subject_timeseries:
    for run in subject_timeseries[subj_id]:
        print(f"""
              subj-{subj_id}; {run}:
              dtype before conversion {subject_timeseries[subj_id][run].dtype}
              dtype after conversion: {converted_subject_timeseries["dict_0"][subj_id][run].dtype}
              """)
