The trace can be magnified in horizontal and vertical direction. The trace data can be scrolled using the scrollbar beneath the trace editor pane.

See the software manual and the text for further details. Screen dump from Ridom TraceEdit (graphical user interface elements like the editor pane are marked by text). A separate text window (data not shown) is used to display the textual data contained in the file. Poor quality data at the start and end of the reading are denoted by gray shading. The trace editor pane shows the trace data, the quality values (if available), the original sequence, the edited sequence and the base positions.

In the file list pane a trace file can be chosen to be displayed in the editor pane. A typical display from TraceEdit is shown in Figure 1. It includes from top to bottom the name of and additional information on the inspected sequence, the menu bar, the file list pane with tool bar, the trace editor pane with tool bar and a status bar. It also enables the user to edit the base calls and save them in SCF file format. The program can be used to locate and delete low quality data at both ends of the sequence (trimming by called Ns or low base quality values if available). Ridom TraceEdit can read ABI and SCF trace files and display their contents. Windows, MacOS X and Linux) and hardware architectures. The platform-independent Java technology was used to provide distributions for various operating systems (e.g. Therefore, new trace editor software-Ridom TraceEdit-was designed and programmed.

Furthermore, it is somewhat cumbersome to install (requires Tcl). Trev has recently become an open source project and, therefore, is no longer advanced and supported in an institutional framework. The first non-commercial trace editor and viewer ted ( Gleeson and Hillier, 1991) was later replaced by the software trev ( Bonfield et al., 2002). These files contain the trace amplitudes, the base calls, their quality values and textual data about the particular sequencing experiment such as its chemistry, machine type and operating conditions, etc. Trace files are stored in proprietary formats, such as those of ABI, or public formats, such as SCF ( Dear and Staden, 1992). Therefore, an increasing number of people need to check the evidence for individual DNA sequences by inspecting the chromatograms (more commonly known as trace files) from which the base calls were deduced. With the sequencing of the human genome and the вЂnew era of molecular medicineвЂ™, one can only expect the use of DNA sequencing to increase further ( Murphy and Eshleman, 2002). Currently, sequencing is being used to identify microbial drug resistance mutations, cancer predisposition, somatic mutations and genetic diseases. These developments have facilitated sequencing and, therefore, it is more widely used. Major advances in DNA sequencing include the development of automated sequencers, discovery of fluorescent terminator chemistry and cycle sequencing. DNA sequencing has been the standard with which other types of DNA testing have been compared.
