0. Add new paths into your .cshrc file
 
 setenv SSW_INSTR "SXT MDI EIT"
 setenv IDL_PATH /home/dana/mpole/anal/:/home/dana/mpole/pkg/v_current:/home/dana/idl/: 
 
 source .cshrc 
 
1. Copy all programs from /disk/hl2/data/nhill/bastille_mdi to your directory where all your 
MDI data is.
 
2. Enter this directory.
 
3. Enter IDL
 sswidl
 
4. Now compile the following programs, changing the paths (it should be your directory) 
 
.compile /disk/hl2/data/pwyper/avg_mdi_region.pro
.compile /disk/hl2/data/pwyper/doy.pro
.compile /disk/hl2/data/pwyper/mdi_rd.pro
.compile /disk/hl2/data/pwyper/display.pro
 
;5. In text editor open mkst07nov04.pro - you should change directory name inside this file and other 
;things specific to you AR
;mkst07nov04 - this program cuts the region of interest from all MDIs
 
.compile /disk/hl2/data/pwyper/mkst07nov04.pro
.compile /home/dana/mpole/anal/vertical_filter.pro
.compile /home/dana/mpole/anal/gradient_mask.pro
.compile /disk/hl2/data/pwyper/auto_mask.pro
.compile /home/dana/mpole/anal/write_msk.pro
 
;2 In text editor open ave_five07nov04.pro - you should change directory names inside the file
 
.compile /disk/hl2/data/pwyper/ave_five07nov04.pro
.compile /disk/hl2/data/pwyper/avg_mdi_region.pro
.compile /disk/hl2/data/pwyper/datestr_conv.pro
.compile /disk/hl2/data/pwyper/imgexp.pro
.compile /home/dana/mpole/pkg/v_current/view2time.pro
 
mkst07nov04  
 
; /disk/data/maria/projects/flares/LCT/LCT4Reu/mag13may05_1.dat
; /disk/data/maria/projects/flares/LCT/LCT4Reu/mag13may05_2.dat
;----------------LCT--------------
 
;3. Open vvar10696.pro in the text editor and change directory names and other things specific to your AR
; This program calculates velocities
 
.compile /disk/hl2/data/nhill/bastille_mdi/vvar10696.pro
.compile /disk/hl2/data/nhill/bastille_mdi/estvel_ar10696.pro
.compile /disk/hl2/data/nhill/bastille_mdi/velocity_dis.pro
.compile /disk/hl2/data/nhill/bastille_mdi/lct.pro
vvar10696,imin=0,imax=1
 
.compile /disk/hl2/data/nhill/bastille_mdi/velocity_dis.pro
 
; 4. Open rdvelstruct - this program shows calculated velocity maps should be changed
.compile  /disk/hl2/data/nhill/bastille_mdi/rdvelstruct.pro
 
;5 Now call rdvelstruct, changing name.
rdvelstruct,name='vel1hrd13jul00_0.dat'
;rdvelstruct,name='vel1hrd13may05_0.dat'
 
;6 Now change the program  vel_jpg - it converts the map you got into jpg
 
.compile /disk/hl2/data/nhill/bastille_mdi/vel_jpg.pro
vel_jpg
vel_jpg,i=0
 
BONUS
 
add into your .idl_startup the following line
 
 device,retain=2
start idl
