Converts a data frame of fluorescence values into PBM condition-wise z-scores using the background fluorescence values.

1	fluorescence_to_zscore_matrix(annotated_fluorescence_matrix)

annotated_fluorescence_matrix

A data frame of fluorescence values and annotations for each probe, such as output by annotate_fluorescence_matrix().

This function normalizes raw fluorescence values against the fluorescence values of the background probes. It first log-transforms all the fluorescence values for a given PBM condition, then calculates a z-score like statistic using the mean and standard deviation of the background probes.

A data frame of PBM condition-wise fluorescence value z-scores.
