You should only have to go through all these steps once -- after that, you only have to do step 3 with each new version of FORWARD
and steps 9-11 if the fortran codes in $FORWARD/FORCOMP change (rare) .
---------------------
1.
make sure you have SolarSoft IDL (SSWIDL) installed
(www.lmsal.com/solarsoft/ssw_install_howto.html)
2. make sure you have all the necessary
packages
IDL
> ssw_upgrade,/spawn,/binaries,/chianti,/eis,/xrt,/eit,/trace,/secchi,/aia,/mdi,/pfss,/nrl,/cds,/swap,/lasco,/loud,/passive_ftp
N.B. If this doesnÕt work check to see if you have Perl installed
3. get latest version of FORWARD [http://www.hao.ucar.edu/FORWARD/TARS], delete (or make sure not in your path) old versions, and expand new tars (for FORWARD, FORWARD_DOCS, and FORWARD_DB). (N.B.:
this step must be redone if any of the tar files have a date stamp later than
the last one your downloaded)
4. create a
working directory FORWARD_WORKING_DIR
5. make sure you have the packages
pointed to in your .cshrc
setemv SSW_INSTR Òbinaries chianti
eis xrt eit trace secchi aia mdi pfss nrl cds swap lascoÓ
6.
make sure you have $FORWARD,
$FORWARD_DB, $FORWARD_DOCS, and $FORWARD_WORKING_DIR and IDL_PATH are all set in
your .cshrc
setenv
FORWARD ~myusername/whereveritis/FORWARD/
(editing
to make the correct path pointing to the FORWARD* directories)
setenv
FORWARD_DOCS ~myusername/whereveritis/FORWARD_DOCS/
setenv
FORWARD_DB ~myusername/whereveritis/FORWARD_DB/
setenv
FORWARD_WORKING_DIR ~myusername/whereveritis/FORWARD_WORKING_DIR/
setenv
IDL_PATH
+${IDL_DIR}/lib:\+$FORWARD/:\+$FORWARD_DOCS/:\+$FORWARD_DB/:\+$FORWARD_WORKING_DIR/
N.B.
This assumes you are running e.g. TCSH not BASH – on a Mac this can be
changed in Terminal Preferences Settings Shell Run Command and type tcsh.
7.
If you don't have <b>IDL_DIR set</b> (check by typing
printenv IDL_DIR) you can set in your .cshrc by
setenv
IDL_DIR directory_where_idl_lives
8.
make sure you have Fortran compiler installed. GFORTRAN is recommended
(https://gcc.gnu.org/wiki/GFortranBinaries ).
9. if using
g77, then edit the makefile in FORWARD/FORCOMP by changing all the
"gfortran" into "g77" (there should be two places, after FC
and after LINK). (N.B.: this step must be redone if forcomp.f or any other
*.f codes change in $FORWARD/FORCOMP directory)
10. go to directory $FORWARD/FORCOMP and in a terminal window compile the
"forcomp" FORTRAN routine with the following command: "make
forcomp".
(it also might work to just type: ÒmakeÓ). (N.B.: this step must be redone if forcomp.f or any other
*.f codes change in $FORWARD/FORCOMP directory)
11. copy the executable forcomp
to your FORWARD_WORKING_DIR (N.B.: this step must be redone if forcomp.f or any other *.f codes
change in $FORWARD/FORCOMP directory).
12. run the tests below outside of FORWARD (just in a SSWIDL session)
13. run FORWARD in a SSWIDL session by
typing
14.
IDL> for_widget,
;*******
TESTS (can
be run in SSWIDL session,
even when FORWARD
not started):
If any of these fail,
be sure you have all the packages
set up as described above.
IDL> aia_lct,wave=193
(this should set AIA color table, you should not get an error.)
IDL> test=get_stereo_lonlat('2010-01-01','A') (this should return
spacecraft position)
IDL> use_network
(this should not give an error - if it does, try ssw_upgrade,/spawn,/loud,/passive_ftp
IDL> test=vso_search('2012-01-01T00:00:00','2012-01-01T00:10:00',instr='aia')
(this should not give an error but acts to query the VSO for data and return information)
IDL> filelocatenew=vso_get(test[0],filenames=filenames,/rice)
this should
download a file with the name of the file now in filenames)
IDL> read_sdo,filenames,header,image
IDL> help,header,image
-you should get something like:
HEADER |
STRUCT |
= -> Array[1] |
IMAGE |
INT |
= Array[4096, 4096] |
