 **What it does**
 
-Accepts a single fastqsanger sample, a set of paired read samples, or a collections of samples along with associated
-SAMtools idxstats and vSNP zero coverage metrics files and extracts information from them to produce an Excel
-spreadsheet containing statistics for each sample.  Statistics include reference, file size, mean read length, mean
-read quality, reads passing Q30, total reads, all mapped reads, unmapped reads, unmapped reads percentage of total,
-reference with coverage, average depth of coverage and good SNP count.
-
-**Required options**
-
- * **Choose the type for files to be analyzed** - select "Single files" or "Collections of files", then select the appropriate history items (single or paired fastqsanger reads or collections of fastqsanger reads and associated idxstats and vSNP zero coverage metrics files) based on the selected option..
+Accepts associated fastq files, SAMtools idxstats files and **vSNP: add zero coverage** metrics files and extracts information from them
+to produce an Excel spreadsheet containing statistics for each sample.  The samples can be single or paired reads, and all associated inputs
+can be either single files or collections of files.  The output statistics include reference, file size, mean read length, mean read quality,
+reads passing Q30, total reads, all mapped reads, unmapped reads, unmapped reads percentage of total, reference with coverage, average depth
+of coverage and good SNP count.
