What Is An .Sam File?

An .sam file is a text-based file format developed by the Sequence Alignment/Map (SAM) format. It is used by bioinformatics applications to store and manipulate large amounts of sequencing data. It is designed to accommodate both the input and output of sequence alignment results, as well as other types of data such as quality scores, alignment statistics, optional parameters, and other annotations. The .sam file format is composed of eleven mandatory fields and several optional fields, which are all tab-delimited. It can be easily manipulated using text-editors, scripts, or programs such as SAMtools. SAM files are also used for visualizing the alignment of sequences, such as in the popular IGV visualizer.

Common Uses Of .Sam Files

.Sam files are text-based files used for DNA sequencing. They contain the mapping of reads to the reference genome.

  • Store the mapping of reads to the reference genome
  • Include information on the quality of the read alignment
  • Can be converted to other file formats such as BAM
  • Used in bioinformatics applications to identify mutations
  • Can be used to generate consensus sequences
  • Help to improve accuracy of the sequence data

How To Open An .Sam File – Step By Step (Windows & Mac)

On Windows

1. Right-click the .Sam file and select “Open With”.
2. If a program is already associated with the file, it will appear in the list. Select it.
3. If no program is associated, browse your computer for a program that will open the .Sam file.

On Mac

1. Right-click the .Sam file and select “Open With”.
2. Select “Other” from the list of applications.
3. Select the program you want to open the file with and click “Open”.

On Android

1. Install a file manager app from the Google Play Store.
2. Open the file manager and locate the .Sam file.
3. Tap the file to open it with the associated program.

On IOS

1. Install a file manager app from the App Store.
2. Open the file manager and locate the .Sam file.
3. Tap the file to open it with the associated program.

Frequently Asked Questions

What is a Sam File?

A Sam file is a type of text file used by the Sequence Alignment/Map (SAM) format. It is commonly used to store genomic data that has been generated by DNA sequencing and processed by mapping software. The SAM file contains metadata about the sequence, such as the source organism and the length of the sequence. It also includes information about the alignment of the sequence, such as the positions of the aligned reads, insertions and deletions, and the quality scores for each aligned read.

What are the Different Parts of a Sam File?

Sam files are composed of several different parts. The header of the file contains metadata about the sequence, such as the source organism, the length of the sequence, and the reference sequence used for alignment. The body of the file contains the aligned reads, which include the read name, the position of the read on the reference sequence, the cigar string (which describes the alignment of the read to the reference sequence), and the quality scores for each aligned read.

What Software is Used to Manipulate Sam Files?

Sam files can be manipulated using a variety of software programs. SAMtools is a widely used open source program for manipulating sam files. It can be used to view, edit, and convert sam files. Other programs such as BWA, GATK, and Picard can also be used to manipulate sam files.

What is a Cigar String?

A cigar string is a string of characters that describes the alignment of a read to the reference sequence. The characters in the cigar string indicate the number of bases that are inserted, deleted, or matched in the alignment. These characters can be used to visualize the alignment of the read to the reference sequence.

What is the Difference Between Sam and Bam Files?

Sam files are text files that contain the metadata and alignment information of a sequence. Bam files are compressed binary versions of sam files and are typically much smaller in size. Bam files are typically used when storing and transferring large amounts of genomic data.

What is the Quality Score of a Read?

The quality score of a read is a measure of the accuracy of the alignment of the read to the reference sequence. Quality scores are encoded as a single ASCII character for each aligned base and range from 0-41. Quality scores can be used to determine the accuracy of the alignment and to filter out low-quality alignments.
