# sand\_compress\_reads(1)

compress sequence data

## NAME

**sand\_compress\_reads** - compress sequence data

## SYNOPSIS

FCsand\_compress\_reads \[-qcivh\] \[infile\] \[outfile\]FT

## DESCRIPTION

**sand\_compress\_reads** reads sequence data in standard FASTA format, and produces output in the compressed FASTA (cfa) format used by the **[sand\_filter\_master(1)](/sand_filter_master/1.md)** and **[sand\_align\_master(1)](/sand_align_master/1.md)**.

If the output file is omitted, standard output is used. if the input file is omitted, standard input is used. After completing the compression, this program will output a summary line of sequences and bytes compressed.

## OPTIONS

- **-q**

  Quiet mode: suppress summary line.

- **-c**

  Remove Celera read ids if data came from the Celera gatekeeper.

- **-i**

  Remove Celera read ids but leave internal ids if the data came from the Celera gatekeeper.

- **-h**

  Display version information.

- **-v**

  Show help text.

## EXIT STATUS

On success, returns zero.  On failure, returns non-zero.

## EXAMPLES

To compress FCmydata.fastaFT into FCmydata.cfaFT:

```

```

-

  % sand\_compress\_reads mydata.fasta mydata.cfa
