Razor sharp traces

A great sequence viewer starts by rendering your traces better than anyone else. Of course it supports the most commonly used sequence file formats like AB1 and SCF files, including sequence quality data that is conveniently displayed on top of your traces. Difficult-to-analyze regions can be scaled horizontally or vertically (by holding Shift). Mark your selection to locate it again later, and when you have found that critical mutation you can print as PDF to create a publication-quality figure.

Drawing conclusions

Viewing your sequence trace files is all about analyzing them. Whether it is to scan for mutations, checking the successful completion of a cloned construct, or detecting SNPs or deletions, 4Peaks helps you quickly draw conclusions. For example, the program gives you quick access to both the nucleotide sequence, as well the translated protein sequence it generates on the fly. This way you immediately know the consequence of a mutation.

Making things easy

4Peaks helps you speed up your sequence analyses in a variety of ways. Trim away low-quality areas with a single click of your mouse, quickly locate one of over 1000+ built-in sequence motifs, or simply start typing a sequence you know it should contain. Doing a BLAST search with your sequence is a matter of seconds, and when you need your eyes on the original sequence, just hit the spacebar to ask 4Peaks to read your DNA trace out loud. Analyzing your sequence has never been so much fun!
