Chromas 2.6.6

Chromas is a free trace viewer for simple DNA sequencing projects which do not require assembly of multiple sequences.

Features:

• Opens .ab1 chromatogram files from Applied Biosystems DNA sequencers.
• Opens SCF and ZTR format chromatogram files created by other sequencers or retrieved from databases.
• Save in .scf or Applied Biosystems .ab1 format.
• Print a chromatogram with options to zoom or fit to one page.
• Automatic removal of low-quality sequence (when quality data is available) or vector sequences.
• Export sequences in plain text, FASTA, FASTQ, EMBL, GenBank or GCG formats, or formatted with base numbering for presentation.
• Copy the sequence to the clipboard in plain text, FASTA or FASTQ format for pasting into other applications.
• Reverse and complement the sequence and chromatogram.
• Search for subsequences by exact matching or optimal alignment.
• Display translations in 3 frames along with the sequence.
• Copy an image of a chromatogram section for pasting into documents or presentations.
• Batch processing, including format conversion, sequence export with vector removal, batch printing and batch export of raw data.
• Enhance .ab1 files using the PeakTrace RP component from Nucleics Pty Ltd to improve peak readability and extract more high-quality bases.

Chromas is free of charge. The PeakTrace RP component requires registration for a free account, and is a paid service after the 40 free units have been used. An introductory discount is available by following the link under the Options menu in Chromas.
