Spatial and temporal image correlation [message #85543]

Dear all,
Hi all,
I have just started using IDL and I’m having hard times even with simple tasks. I’m trying to do the following task:

I have 12 folders (2001, 2002 ….2012) and in each folder I have 35 files .dat of anomalies (7 months NDVI, 7 months Surface temperature and so on) and I would like to do a correlation (pixel by pixel) for each index in each month for each year.

After that I want to make one plot per year: each index in a different column and each row representing a different month.

I started writing the code bellow, but I’m confused now. I think the next step would be REFORM the images, so for each image I will have a vector that I could use to do the correlation.
Is there anyone that could help me on that?

Thanks a lot,

PRO ImgCorr,
CD, 'C:\Anomalies\year'
theseFiles = FindFile('*.dat', Count=numFiles)
Print, 'Number of files found: ', numFiles
FOR j=0,numFiles-1 DO BEGIN
OpenR, lun, theseFiles(j), /Get_Lun
File = fltarr(620, 500)
ReadU, lun, File
JustNumbers= where(File eq -9999, count)
File[JustNumbers]=!VALUES.F_NAN
*
*
*
*
Free_Lun, lun
ENDFOR
END
