This topic shows a command-line summary for the program. In the summary, the capitalized letters in the qualifier names are the letters that you must type in order to use the parameter. If a program is not trivial, this topic tells where the ideas and the code came from. If there are publications on which the program is based, they are cited here unless they have been cited in other topics. If the code did not originate at GCG, we will cite the code's author here.
Some programs require nonsequence data.
These data are normally read into the program automatically from data files. For instance, the restriction mapping programs all require a file called Enzyme. Dat, which contains the names of restriction enzymes and their recognition sites. Normally these files are read from a public data directory and you need not provide them or even know about them. But if, for any reason, you wish to use your own data, you can use the Fetch program to copy the file and use an editor to modify it to suit your needs.
