NAME
splitcorrection - Produce multiple command files for running ctfphase-
flip in parallel
SYNOPSIS
splitcorrection [options] <ctfphaseflip command file>
DESCRIPTION
splitcorrection will take a command file for running the ctfphase-
flip(1) program and produce multiple command files that can be run in
parallel by Processchunks.
The only argument that the typical user needs to give is -m to specify
the number of views to be processed by each chunk. The default value
is printed out by the program’s usage statement. Thus, a typical com-
mand might be
splitcorrection -m 6 correction.com
After giving this command, there will be a series of command files cor-
rection-nnn.com to compute the chunks, a file correction-start.com, and
a file correction-finish.com to finish the task and clean up intermedi-
ate files. One can then enter
processchunks machine_list correction
where "machine_list" is the comma-separated list of machines to use.
Options
When the program is invoked with no arguments, it gives a usage state-
ment that shows the default values for these options.
-m <value>
Set the number of views to be processed per chunk to the given
value (the default is 5 ).
FILES
The finishing command file deletes all the command and log files for
the chunks after collecting minimun, maximum, and mean density informa-
tion from the log files.
