Thanks for the the info!

if you look at the ftp the tilesV for h10 are going up to 11...so I have
to inplement a handling fot this!
I'll look for it tomorrow (I'll try to fix it in version 0.2-11)
If you want to run it in the mean time do it row by row or col by col
... http://remotesensing.unh.edu/modis/modis.shtml

  Matteo,

  Thanks for the tip. The problem was in my connection. After probing
the ftp again, behind a proxy, all the contents were shown (including
hdf and xml files). I reported it to the IT guys and everything is fine
now.

  However, I received an error after trying to reproduce your
suggestion:

> library(getMODIS)
Loading required package: RCurl
Loading required package: bitops
> 
getHDF('/Users/thiago/Downloads/MODIS/images/',product="MOD17A2",tileH=10:14,tileV=7:14,startdate="2005.01.01",enddate="2006.12.31")
 Loading required package: audio
No Collection spezified used the newest for MOD17A2 : 005 

  (it successfully download tiles V from 7 to 11 inside "first" tile H
(which is 10)). Then, the error message:

  Error in dates[[z]][i, j + 1] <- HDF : replacement has length zero

  I'm running latest R version and updated packages in Mac. Below is my
sessio info:

> sessionInfo()
R version 2.13.2 (2011-09-30)
Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit)

locale:

attached base packages:

other attached packages:

loaded via a namespace (and not attached):

  Any tip on what might be causing this error?

  Best wishes,

  Thiago.
