MIRIA is a user-ferendly webserver that integrates statistics and visualization techniques, to facilitate comprehensive analysis of RNA editing sites data identified by other pipelines and software. The MIRIA provides several analysis functions, including RNA editing types statistic, genomic feature annotation, editing level statistic, editing sites distribution, tissue-specific analysis and conservation analysis.


Input File

MIRIA required user to upload a compressed file (.zip format) containing all RNA editing files of different mammals. The architecture of the zip file has two layers. The first layer contains all species folders (e.g., human, mouse, rat) and the second layer, inside each species folder, contains all RNA editing files of this species (e.g., tissue1.res, tissue2.res, tissue3.res) (Figure 1). The format of the single RNA editing file (.res) is listed below (Table 1).

Figure 1 Figure 1. The example input file of MIRIA

Chromosome Location (0 based) Location (1 Based) Type Supporting information Strand AD:DP
chr1 1266631 1266632 TC 3 - 5:9
chr1 1280297 1280298 AG 2 + 2:2

Table 1. The format of a single RNA editing file. Chromosome: Name of chromosome. Location (0/1 base): Position of the editing site in the chromosome. Type: Type of the identified editing site (e.g. AG means ’A-to-G’, etc.). Supporting information: Number of supporting reads for this editing site. Strand: Possible values are: ’.’, ’+’, and ’-’ which correspond to ’uncertain’, ’positive strand’, and ’negative strand’ respectively. AD:DP: Number of reads that has this editing site and the number of reads that cover this location. This file is the output file of RNA editing sites identification tool, SPRINT. Users need to convert other RNA editing sites file format to this format before uploading input file.

Data Uploading

Users can analyze their data by uploading their .zip input file in MIRIA analysis page (clicking ANALYSIS link in navigation bar)(Figure 2).

Job Status Checking

After analysis job submission, a job id will be assigned (Figure 3) and users can check their job status using this job id by clicking check you job status link in analysis page (Figure 4).
