Welcome to tar2h5

Convert Tape ARchives to HDF5 files

• archive_checker - check how many files can be extracted from the input tar file
• archive_checker_64k - check if any files within input tar files larger than 64 KB
• h5compactor - convert input tar file into hdf5 file, all files within tar file should smaller than 64KB, using small files name as dataset names.
• h5compactor-sha1 - convert input tar file into hdf5 file, all files within tar file should smaller than 64KB, using small files sha1 values as dataset names.
• h5shredder - convert input tar file into hdf5 file, no file size limitation, concatenate data and offsets into 4 seperate arrays for better randomized access
