 **Output**
-- bestMerge targets file, containing all the highest scoring targets, in terms of CFD and targets with the lowest combination of mismatches and bulges (with preference to lowest mismatches count), each genomic position is represent by one target
-- altMerge targets file, containing all the discarded targets from the bestMerge file, each genomic position can be represented by more than target

+As a given genomic region may have multiple alignments, CRISPRme outputs two lists of candidate off-target sites: 
+- The "integrated_results" file reports a single candidate off-target per genomic region, merging all possible off-targets within 3 bp (by default, adjustable parameter), and integrates annotation information if provided. The nominated off-targets are selected and sorted based on highest CFD score (by default, users can select other criteria), and when the CFD score is identical, the reference alignment is favored over alternative alignments. CRISPRme only reports candidate off-targets corresponding to observed haplotypes. A more extensive description and explanation of all the columns in this main CRISPRme results file can be found in [Supplementary Table 1 of our CRISPRme paper](https://static-content.springer.com/esm/art%3A10.1038%2Fs41588-022-01257-y/MediaObjects/41588_2022_1257_MOESM1_ESM.pdf).
+- The “all_results_with_alternative_alignments” file contains all the candiate off-targets not included in the first file. This file preserves alternative alignments as well as those containing other variants with lower CFD scores.
