How to use it

You don't have to read a manual in order to use this program. A graphic interface is available to help you to generate the command line.

The same program acts both as a GUI and command line tool. The difference is made by the way you start the program:

Command Line Generator (graphic) mode: double click program's icon.
Format Converter: start the program from a DOS box/DOS script and pass some arguments into the command line

Supported command line switches:

	Switch	Description
	--inputfile	The input sample. The following input formats are supported: SCF, ABI, FASTA, SEQ, TXT, GBK.
	--outputfolder	The folder where the output file will be written. Default=application's folder.
	--trimends	The program will automatically trim low quality ends (if the input sample has QV info embedded).
	--writelog	Write details about how the conversion went. Useful to see possible errors you may have during conversion. The log will be written in the output folder.
	--outputformat	The following output formats are supported: SCF, FASTA, SEQ, TXT, GBK.
	--windlength	WindowLength parameter for trimming engine.
	--goodqvtresh	GoodQVTresh parameter for trimming engine.
	--goodbasesno	GoodBasesNo parameter for trimming engine.

Note: You don't have to write theses switches by hand in your script file. Let the GUI to generate them for you.

Example of scripts

How to convert all SCF files in a folder to FASTA:

Let's say that you have 1000 SCF sample file in the 'c:\samples' folder and you want to put the output (FASTA format) in the 'c:\samples\output' folder.

Create a new text file with Notepad and copy the code from the black box below in it. Save the file as 'convert_all.cmd' and double click it to execute it. In few seconds you will have all SCF files converted to FASTA.

for %%F IN (c:\samples\*.scf) DO Convertrix.exe --InputFile="%%F" --OutputFormat=fasta --OutputFolder="c:\samples\output" --enable-TrimEnds --enable-WriteLog
