Abstract

Hardklör and Krönik are software tools for feature detection and data reduction of high-resolution mass spectra. Hardklör is used to reduce peptide isotope distributions to a single monoisotopic mass and charge state, and can deconvolve overlapping peptide isotope distributions. Krönik filters, validates, and summarizes peptide features identified with Hardklör from data obtained during liquid chromatography mass spectrometry (LC-MS). Both software tools contain a simple user interface and can be run from nearly any desktop computer. These tools are freely available from http://proteome.gs.washington.edu/software/hardklor.

摘要

Hardklör和Krönik是用于高分辨率质谱特征检测和数据缩减的软件工具。Hardklör用于将肽同位素分布缩减为单一的单同位素质量和电荷状态，并且能够对重叠的肽同位素分布进行去卷积处理。Krönik对通过Hardklör从液相色谱质谱联用（LC-MS）过程中获得的数据所识别的肽特征进行过滤、验证和汇总。这两个软件工具都具有简单的用户界面，并且几乎可以在任何台式计算机上运行。这些工具可从http://proteome.gs.washington.edu/software/hardklor免费获取。
