Permute
The Permute java application permutes the storage order of a Pgh1.0
dataset. Permitted permutations are to txyz xyzt, or xytz order.
A Pgh1.0 txyz dataset can be used as input to the SliceApp or RoiApp
timeseries viewers.
The Permute java application invokes the Fiasco4.x permute function
to do the permutation. (Fiasco4.x permute can do any permutation, this
java wrapper only permits txyz/xyzt/xytz.)
For more information about the Fiasco4.x permute function see the
fiasco permute help page.
java Permute
This starts up the java interpreter and runs the Permute
application. You need to have
setup your environment for java
in order for this to work.
- Input File
Enter the name of the Pgh1.0 dataset that you want to permute.
You don't need to enter the .mri or .dat file extension in this field.
The header and/or data file may be compressed.
- Output Directory
Enter a name for the Pgh1.0 dataset that will be created.
You don't need to add a .mri or .dat extension. By default,
the header file will have the .mri extension and the data file
will have the .dat extension.
- Temp Directory
The permute program may need temporary space.
/tmp is NOT a good
choice. Try /ccn_scratch1/imaging. The permute
program will make its own directory and delete it when done, in whatever
directory you enter as the Temp Directory.
- Memory available
In order to efficiently permute the data, 1 copy of your dataset needs to
be in memory.
(Example: a 64 64 20 1000 dataset needs 157MB).
hydra has 843MB total memory (192RAM + 200 swap partition + 451 disk swap).
Currently, if you do not have sufficient memory to hold 1 copy of the dataset
in memory, the program will exit.
- Permutation
Choose which permutation of the data you want; only xyzt, txyz, and
xytz are currently supported. (If your input dataset has a v dimension
of length 1, this will automatically be added to the permutation.)
- Run
Run starts the permute program.
- Close
Close will kill the entire application.
- Log
Use this dialog box to log program output to a logfile.
- Help
Help will start up netscape on whatever machine you are running the
application on, with the html help document for Permute.
All CCN lab java help documents are also available at a
kraeplin java doc site.
