So, to specify what the mismatch is, there is another tag in the SAM file, called MD ( String for mismatching positions). To keep in mind is the M can contain mismatch. For other types of alignments, the interpretation of N is not de ned ". " For mRNA-to-genome alignment, an N operation represents an intron. My understanding is I is similar as N, only difference is in length.
To note here is the 'M/I/D/N', which means alignment match (can be a sequence match or mismatch), insertion to the reference, deletion from the reference and skipped region from the reference. The SAM specification file already tells the details of CIGAR line. Two places to get the info: 1) from CIGAR line. The variation information is already stored in the SAM file (since it's alignment result).

Update: The snip code to extract unique mappers can beĢ. 256 or 272 depending on which strand it mapped to), so use snip like awk '' One is by the FLAG field multi-mapped reads contain bit of 0x100 in their FLAG tag (e.g. " SAM format: single vs multiple hits?", " For SAM files, if a query is aligned to multiple positions would I have multiple entries for the same query or would I get multiple alignment positions in the same entry for the query?"), I'd like to address based on my understanding to the SAM specification.ġ. Īccording to the common questions asked (e.g. Program console output and metrics files.First of all, read the SAM specification file carefully, which ought to contains all pieces of information you need.When asking a question about a problem, please include the following: Attempt to resolve or at least understand any problems reported.

If not, you may need to update your version see the Oracle Java website to download the latest JDK. If the output looks something like java version "1.8.x", you are good to go. To check your java version by open your terminal application and run the following command: java -version Unlike C-compiled programs such as Samtools, Picard cannot simply be added to your PATH, so we recommend setting up an environment variable to act as a shortcut.įor the tools to run properly, you must have Java 1.8 installed. Open the downloaded package and place the folder containing the jar file in a convenient directory on your hard drive (or server). The file name will be of the format picard-tools-x.y.z.zip. You can download a zipped package containing the jar file from the Latest Release project page on Github. The Picard command-line tools are provided as a single executable jar file.
