Hash_exp

NAME

hash_exp -- produces an index for a file of concatenated experiment files.

SYNOPSIS

hash_exp exp_archive

DESCRIPTION

hash_exp adds a hash-table index on to the end of a concatenated file of experiment files. It's purpose is simply to provide random access to experiment files while also reducing the number of separate disk files.

The hash_list program will list the contents of the hashed archive. The entry names stored in the archive are taken from the ID lines in the experiment files rather than their original filenames.

Within Gap4 you can assemble a hashed experiment file archive and it will automatically assemble all files within it. For finer grain control use hash_list to produce a file of filenames and then edit this accordingly before supplying it as a "fofn" to gap4. In this case you will also need to configure Gap4 to set the EXP_PATH environment variable to contain HASH=exp_archive_filename.
