Sometimes the best solution isn't a Stata solution; for this kind of problem I usually invoke some other software. For instance, Stat/Transfer will convert a .csv file to a Stata file while retaining only selected variables, and does not require vast RAM. Or, you can open in Excel, delete a few columns, and save as a new .csv file; Excel also buffers to disk and hence needs less RAM. (If you go the Excel route, though, be exceedingly careful, because Excel makes it too easy to corrupt your data - for instance, by sorting a single column.) hth, Jeph On 7/20/2010 7:38 PM, enewton@notes.cc.sunysb.edu wrote:Hi, I'm new to Stata, and new to this listserv. I'd like to load a very large ASCII .csv file into a .dta Stata file but it keeps bumping up against the 1.1g memory limit and Stata suggests I "drop some observations or variables." My question is how one can load just a portion of an ASCII file--for example, the specific variables of interest, or only those observations where variable1=xyz--so as to end up with a more manageable Stata file. A second question is why I can't set memory higher than about 1.3g, when I have about 100g of space left on the computer, but that's probably something my computer& I need to work out between ourselves.
