Hi,Everyone
why the routine gives me an error message:
% Array subscript for X must have same size as source expression.
************************************************************ *

pro timestrap
set_plot,'win'
rawfile=file_search('D:\20130313\LuckImage_3\*.fits') & DEVICE,DECOMPOSED=0 & LOADCT,0
data=fltarr(400,300,242)
window,1,xs=350,ys=500
for i=0,242-1 do begin
a=readfits(rawfile[i],h) & a=a/mean(a)*500 & a1=readfits(rawfile[i+3],h) & a1=a1/mean(a1)*500
log=0
if (log eq 1) then begin
endif else begin
a=a1-a & jz=15
if(max(a)gt jz)then a(where(a gt jz))=jz
if(min(a)lt -jz)then a(where(a lt -jz))=-jz
endelse
a=a[524:*,30:530-1] & b=fltarr(750,750) & b [125:624,125:624]=a & b=rot(b,-30)
b=b[275:674,225:524]
data[*,*,i]=b
endfor
cc=fltarr(250,460) & for i=0,22 do cc[*,i*20+1:i*20+19]=data[150:*,120+7:138+7,i*4+10]& tvscl,cc
end

You could just do "help" for both the left hand side and the right hand side of the assignment that gives the error.

Like

IDL> help, b[125:624,125:624], a

or

IDL> help, cc[*,i*20+1:i*20+19], data[150:*,120+7:138+7,i*4+10]

depending on which line has the error.
