+The meanings of the columns are as follows.
+
+\begin{itemize}
+\item \textbf{Row}: The row number in the table;
+\item \textbf{File}: The filename of fastq file;
+\item \textbf{Label}: Assigned label;
+\item \textbf{Reads}: The total read count in the fastq file;
+\item \textbf{Mapped}: Reads that can be mapped to gRNA library;
+\item \textbf{Percentage}: The percentage of mapped reads;
+\item \textbf{TotalsgRNAs}: The number of sgRNAs in the library; 
+\item \textbf{ZeroCounts}: The number of sgRNA with 0 read counts;
+\item \textbf{GiniIndex}: The Gini Index of the read count distribution. Gini index can be used to measure the evenness of the read counts, and a smaller value means a more even distribution of the read counts.
