## Function

ACD compiler on-screen trace

## Description

Acdtrace reports the processing of lines in an ACD file, including the resolution of any variables or ACD functions.

Acdtrace does not have its own command line. Instead, it will run the command line of any EMBOSS program by reading its ACD file and processing the command line and user responses in exactly the same way as the true program.

Acdtrace uses a very simple method. The first command line parameter is the name of the EMBOSS program to be compiled. All other command line parameters and qualifiers are processed by that program's ACD file.

## Usage

Here is a sample session with acdtrace

    % acdtrace antigenic
    Finds antigenic sites in proteins
    Input protein sequence(s): tsw:actb1_fugru
    Minimum length of antigenic region [6]:
    Output report [actb1_fugru.antigenic]:

Go to the input files for this example
Go to the output files for this example

## Command line arguments

The first parameter is the name of the program to compile. All other command line parameters and qualifiers are defined for that program - see the documentation for the program of choice.

## Output file format

The output file is empty, but any format available to the specified program can be used.

### Output files for usage example

### File: actb1_fugru.antigenic

## Data files

Acdtrace will use any data files specified in the ACD file of the specified program, but will ignore any data files that are only used directly by the program's code.

EMBOSS data files are distributed with the application and stored in the standard EMBOSS data directory, which is defined by the EMBOSS environment variable EMBOSS_DATA.

To see the available EMBOSS data files, run:

    % embossdata -showall

To fetch one of the data files (for example 'Exxx.dat') into your current directory for you to inspect or modify, run:

    % embossdata -fetch -file Exxx.dat

Users can provide their own data files in their own directories. Project specific files can be put in the current directory, or for tidier directory listings in a subdirectory called ".embossdata". Files for all EMBOSS runs can be put in the user's home directory, or again in a subdirectory called ".embossdata".

The directories are searched in the following order:

- . (your current directory)
- .embossdata (under your current directory)
- ~/ (your home directory)
- ~/.embossdata
