Re: Error in concatenation of multiple files

Dear Mary,

Thanks for your reply.
My data files are very long time-series and I need a part of it only.
So, reading the whole time-series, as you have suggested in earlier email, is not a good option as my PC's memory is not supporting that!!
Is there any other way to solve the problem?
I am using ndtooned and onedtond functions afterward to rearrange the input array.
Thank you once again.

Regards,
Abhik

You are subscripting the leftmost (time) dimension to be 0:4017, which is why you are getting 4018 points:

> X = fall[:]->xanom(0:4017,{latS:latN},:)

Try

> X = fall[:]->xanom(:,{latS:latN},:)
