SAM Sequence file
File type: Various data file
A .weightoutput file is a text output file produced by the SAM (Sequence Alignment and Modeling system) bioinformatics software.
It contains sequence weights calculated by the buildmodel tool's internal weighting option.

The SAM (Sequence Alignment and Modeling system) package uses buildmodel to construct sequence models. A .weightoutput file records the weights assigned to the input sequences during this process.
A .weightoutput file is present when both internal weighting and the print_all_weights option are enabled. It is an auxiliary result of the model-building process rather than a standalone sequence or model file.
SAM is available for Linux and Unix systems. The weightoutput format is a specialized SAM output format and is intended for use with the results of the software's model-building workflow.
A .weightoutput file is a text file, so its contents can be inspected with a text editor on Linux or Unix. The file is generated by SAM's buildmodel tool and is primarily intended to be read as part of that workflow.
This file contains sequence-weight output rather than data intended for conversion to another standard format. It can be retained as text or regenerated by running SAM's buildmodel tool with internal weighting and print_all_weights enabled.
