 #### Correlation between Ibaq and MaxQuant(Ibaq)
 
-For `PXD007683-LFQ`, we will normalize the MaxQuant Ibaq values of the proteins by dividing it by the total sum of that sample. Then compare the correlation between the log values of it and the log values of IbaqNorm.
+For `PXD007683-LFQ`, we will normalize the MaxQuant Ibaq values of the proteins by dividing it by the total sum of that sample. Then, we use quantmsio to convert the results report from quantms, and subsequently apply the median-cov method to calculate the iBAQ values in the results report. Finally, we compare the correlation between the log values of it and the log values of IbaqNorm.

+Next, for the peptide table of MaxQuant, we recalculated the Ibaq values using `ibaqpy`. Then compare the correlation between the log values of it and the log values of IbaqNorm. `Cov` is used to reduce the impact of missing values, adding an extra step compared to directly calculating the iBAQ values, which leads to some differences between its iBAQ values and those calculated directly.
