19.6. ADVANCED SLICING WITH X SLICER 229
In addition to using the big file button, you may want also want use the save slicer file button
(located in the x handle slice window – see Section 12.2). See Section 19.6.9 for details on its
use.
19.6.9 The save slicer file button and slicer to cia
If you have a large data set, you can simply slice them with x slicer, working on data with
the x handle slice window. Only the last action is different. Instead of hitting the ‘Continue’
Button, hit the ‘Save Slicer file’ button. You will then be asked to enter a SSCD name. Once
you have done that, hit the ‘OK’ button. x slicer creates a file named sscd name.sli. Thisfile
contains the current x slicer settings, but no data.
To use this file, just quit x slicer and even quit CIA in order to free all memory. Then enter
CIA again and type:
CIA> COMMON slicer_data,toto
CIA> slicer_to_cia,‘sscd_name.sli’,dir_sli=‘directory_of_sscd_name.sli’, $
CIA> sscd, dsd, /save
All your SCDs will be created, just as if you never exited x slicer. Moreover, SSCD and
DSD variables will contain your created SSCD and DSDs.
IMPORTANT: check first that the data you entered in x slicer are still in the same directories,
because the .sli file does not contain any data – it simply informs the slicer to cia routine
where they may be found.
19.6.10 Getting your SSCDs
To work on your data after having exited x slicer, there are two ways to proceed:
• use the routine sscd read to read them back from the disk. This is time consuming if you
have big SSCDs.
• enter the command:
CIA> print,sscd_list()
Pick the sscd that you are interested in.
