SAM files and BAM files contain the same information, but in a different format.
WHAT IS BAM FILE FORMAT SOFTWARE
If you are writing software to read SAM or BAM data, our C++ libStatGen is a good resource to use. The current definition of the format is at.
WHAT IS BAM FILE FORMAT ARCHIVE
In the future, SAM will also be used to archive unaligned sequence data generated directly from sequencing machines. Most often it is generated as a human readable version of its sister BAM format, which stores the same data in a compressed, indexed, binary form.Ĭurrently, most SAM format data is output from aligners that read FASTQ files and assign the sequences to a position with respect to a known reference genome. The SAM Format is a text format for storing sequence data in a series of tab delimited ASCII columns.
BAM definitions can also contain PivotTable layouts. Numeric range dimension - Used to categorize aggregations based on friendly names of given numeric ranges.īAM definitions can contain alert definitions that are defined in the views. Time dimension - Used to create aggregations across defined time segments. Data dimensions are based on the value of string formatted data items in the BAM activity. Progress dimension - Represents the creation of aggregations with respect to the progress of activities that are still in process.ĭata dimension - Used to categorize an aggregation. Measures - A set of numeric values in an Analysis Services (OLAP) cube based on a column in the fact table of the cube. You can use a group as either the starting or ending business milestone of a duration.Īggregations - These can be either real-time aggregations (RTAs) or scheduled aggregations (also referred to as online analytical processing (OLAP)), and consist of the following items: Milestone groups - Sets of business milestones.
WHAT IS BAM FILE FORMAT HOW TO
For more information about aliasing, see How to Rename View Items.ĭuration - The time period over which the activity is monitored. For example, a developer may define a data item called “LName.” You can create an alias so that the “LName” is displayed as “Last Name” when viewing the BAM live data. In a view you can define the following business processes:Īliased business data - Aliasing allows you to apply friendly names to data items. BAM supports the definition of one or more views per activity. Views consist of filtered data, aggregations of the filtered data, and ways of presenting the filtered data, such as a PivotChart report.
Views – Views define the set of users that can access the data defined by the business activity. For information about adding a business activity to a definition, see How to Define a Business Activity. All other items in the definition are optional. You can also manually create an XML file that follows the BAM schema, but this is not a recommended way to create the BAM definition as it does not provide a definition that has been validated.īAM definitions can contain the following items:īusiness activities - A valid BAM definition must contain a business activity (also referred to as a BAM activity).
