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.
