Please check the official document for the Suzaku analysis,
"the ABC guide of Suzaku"
(http://heasarc.gsfc.nasa.gov/docs/suzaku/analysis/abc/),
or "the first step manual (Only in Japanese as of 2006 Dec. 18)"
(http://cosmic.riken.jp/suzaku/help/guide/index_e.html).

1. 
Before starting the Suzaku analysis, you need to install the
latest version of the HEADAS package from the following URL.
http://heasarc.gsfc.nasa.gov/docs/software/lheasoft/

Please check important information in the following WWW page.
You can check observation log via following www page:
 http://darts.isas.jaxa.jp/astro/tables/SUZAKU_LOG.html

Please check important events in the operation during your observation.
 http://www.astro.isas.jaxa.jp/suzaku/log/operation/
 http://www.astro.isas.jaxa.jp/suzaku/log/hxd/
 http://www.astro.isas.jaxa.jp/suzaku/log/xis/

Please check the limitation of the pipe-line products.

It is better to check announcements from the detector's team.

2.
Obtain the desired data set of your observation from
the DARTS at ISAS/JAXA, Japan (http://darts.isas.jaxa.jp)
or the HEASARC FTP site(ftp:legacy.gsfc.nasa.gov)
When your OBS_ID is 101005040, for example, you can download whole
directory tree with the wget command as follows:

unix% wget -rL -nH --cut-dirs=4 \
      ftp://darts.isas.jaxa.jp/pub/suzaku/rev1.2/101005040/
Then, you will get the following directory tree:
(the "hxd" subdirectory is omitted in this document)

auxil/
   ae101005040.att.gz   ae101005040.cat.gz
   ae101005040.ehk.gz   ae101005040.hk.gz
   ae101005040.mkf.gz   ae101005040.orb.gz
   ae101005040.tim.gz
xis/event_uf/
       ae101005040xiN_0_5x5n000z_uf.evt.gz (N=0,1,2,3 for XIS-0,1,2,3)
xis/event_cl/
       ae101005040xiN_0_5x5n000a_cl.evt.gz (N=0,1,2,3 for XIS-0,1,2,3)
xis/products/
       ae101005040xiN_0.pi
       ae101005040xiN_0.lc
       ae101005040xiN_0_pi.gif
       ae101005040xiN_0_lc.gif
xis/hk/
       ae101005040xiN_0.hk.gz

Event files in xis/event_cl/ are the cleaned event files,
which you can use for your QL analysis.

3.
Use xselect to make, display & save products from cleaned event files.

xsel:SUZAKU-XIS-1-STANDARD > read event
  > Enter the Event file dir >[] .
  > Enter Event file list >[] ae101005040xi1_0_5x5n000a_cl.evt.gz
xsel:SUZAKU-XIS-1-STANDARD > extract all
xsel:SUZAKU-XIS-1-STANDARD > saoimage
xsel:SUZAKU-XIS-1-STANDARD >  plot curve
xsel:SUZAKU-XIS-1-STANDARD >  plot spectrum
xsel:SUZAKU-XIS-1-STANDARD >  save spectrum

4.
In order to enjoy spectral fitting and so on,
get the newest CALDB files for the analysis from
       http://www.astro.isas.jaxa.jp/suzaku/caldb/ or
       http://heasarc.gsfc.nasa.gov/docs/heasarc/caldb/suzaku/

5.
When you want to make response/arf files for the spectral analysis,
use the ftools XISRMFGEN and XISSIMARFGEN.
