Re: getfilevardims() while Handling Multiple File

Hello again,
In this case, the error message is telling you what the problem is.
infile1 is a list, and getfilevardims does not support lists. Also, it is
inefficient in NCL to dimension reorder upon reading in an array. I think
the best way to accomplish what you want is to do the following:

fpath = systemfunc ("ls
/gpfs2/home/kiran/freerun/t62/monthly/time_mean.*01.nc")
infile1= addfiles(fpath,"r")
tw=infile1[:]->temp(0:99,0,:,:)
dims = getvardims(tw)
t = tw($dims(1)$ |:,$dims(2)$ |:,{$dims(0)$ |:})
delete(tw)

Good luck,
Adam
