# ### Run the analysis
# /media/andrey/My Passport/GIN/Anesthesia_CA1/validation/calcium_imaging
# It creates a data frame *df_estimators* that contains basic information regarding stability of the recordings, such as 
# 
# - total number of identified neurons,
# - traces and neuropils median inntensities for each ROI
# - their standard deviation
# - skewness of the signal
# - estamation of their baseline (defined as a bottom quartile of signal intensities) 
# - their temporal stability (defined as the ratio between median signals of all ROIs in the first and the second parts of the recording)
