| 8 Description: Reorders reads randomly, keeping pairs together. | |
| 9 Unlike Shuffle, Shuffle2 can write temp files to handle large datasets. | |
| 10 | |
| 11 Usage: shuffle2.sh in=<file> out=<file> | |
| 12 | |
| 13 Standard parameters: | |
| 14 in=<file> The 'in=' flag is needed if the input file is not the first parameter. 'in=stdin' will pipe from standard in. | |
| 15 in2=<file> Use this if 2nd read of pairs are in a different file. | |
| 16 out=<file> The 'out=' flag is needed if the output file is not the second parameter. 'out=stdout' will pipe to standard out. | |
| 17 out2=<file> Use this to write 2nd read of pairs to a different file. | |
| 18 overwrite=t (ow) Set to false to force the program to abort rather than overwrite an existing file. | |
| 19 ziplevel=2 (zl) Set to 1 (lowest) through 9 (max) to change compression level; lower compression is faster. | |
| 20 int=auto (interleaved) Set to t or f to override interleaving autodetection. | |
| 21 | |
| 22 Processing parameters: | |
| 23 shuffle Randomly reorders reads (default). | |
| 24 seed=-1 Set to a positive number for deterministic shuffling. | |
| 25 | |
| 26 Java Parameters: | |
| 27 -Xmx This will set Java's memory usage, overriding autodetection. | |
| 28 -Xmx20g will specify 20 gigs of RAM, and -Xmx200m will specify 200 megs. | |
| 29 The max is typically 85% of physical memory. | |
| 30 -eoom This flag will cause the process to exit if an out-of-memory | |
| 31 exception occurs. Requires Java 8u92+. | |
| 32 -da Disable assertions. | |
| 33 | |
