 ** Filtering reads
 
 It is possible to extract all segmented or unsegmented reads, possibly to give them to  other software.
-Runing Vidjil with =-U= gives a file =out/basename.unsegmented.vdj.fa=, with all segmented reads.
+Runing Vidjil with =-U= gives a file =out/basename.segmented.vdj.fa=, with all segmented reads.
 On datasets generated with rather specific V(D)J primers, this is generally not recommended, as it may generate a large file.
 However, the =-U= option is very useful for whole RNA-Seq or capture datasets that contain few reads with V(D)J recombinations.

 However, they are very useful in some situations, especially to understand why some dataset gives poor segmentation result.
