  Dear Barak,

  If you are also accepting suggestions about errors, please let me share my experience with your script. I have received an error which appears to be related to a argument of package RCurl. Below, please take a look at my attempt to use your script:

> setwd("/Users/thiago/Downloads/MODIS/images/")
> source("/Users/thiago/Downloads/MODIS/ModisDownload.R")
> GPP <- "ftp://e4ftl01.cr.usgs.gov/MODIS_Composites/MOLT/MOD17A2.005/"
> MRT <- "/Applications/MRT/bin/"
> library(RCurl)
Loading required package: bitops
> library(raster)
Loading required package: sp
raster version 1.9-32 (24-October-2011)
> ModisDownload(FTP=GPP,h=c(10,14),v=c(7,14),dates=c("2010.01.01","2010.12.31"),mosaic=F,proj=F)
Error in download.file(url = paste(FTP, "/", dirs[i], "/", ModisName,  : 
  cannot open URL 'ftp://e4ftl01.cr.usgs.gov/MODIS_Composites/MOLT/MOD17A2.005//2010.01.01/-rw-r--r--  1 90  395831 Feb  4  2010 MOD17A2.A2010001.h10v07.005.2010035143552.hdf'
In addition: Warning message:
In mapCurlOptNames(names(.els), asNames = TRUE) :
  Unrecognized CURL options: ftplistonly

  Looking at the script, this line seems to be the source of the error:

  getlist <- strsplit(getURL(paste(FTP,"/",dirs[i], "/", sep=""), .opts=curlOptions(ftplistonly=TRUE)), "\r*\n")[[1]]

  And checking the arguments of curlOptions, "ftplistonly" doesn't appear to be available:

  As usual, output of sessionInfo:

  Any tips?

  Thank you and best wishes,
