<div dir="ltr">Hi Melanie,<div>regCoef operates on the rightmost dimensions of the two input arrays, and expects those two rightmost dimensions to have the same size. See the documentation here:</div><div><a href="https://www.ncl.ucar.edu/Document/Functions/Built-in/regCoef-1.shtml">https://www.ncl.ucar.edu/Document/Functions/Built-in/regCoef-1.shtml</a><br></div><div>referring specifically to the Arguments - y section near the top.</div><div><br></div><div>Thus, assuming your EOF/principal component timeseries was computed over the TIME1 dimension, you should change this:</div><div>eof_regres(ne,:,:) = (/ regCoef(eof_ts(ne,:), x2(TIME1|:,DEPTH1_1|:,LAT|:,LON|:))/)<br></div><div>to this:</div><div>eof_regres(ne,:,:) = (/ regCoef(eof_ts(ne,:), x2(DEPTH1_1|0,LAT|:,LON|:,TIME1|:))/)</div><div>(Note that I also changed "DEPTH1_1|:" to "DEPTH1_1|0" so that the first and only index is chosen, that way the array returned to the lefthand side of the equal sign will be dimensioned lat (100) x lon (100).)</div><div><br></div><div>If you were using regCoef_n, you could do this:</div><div>eof_regres(ne,:,:) = (/ regCoef_n(eof_ts(ne,:), x2(TIME1|:,DEPTH1_1|0,LAT|:,LON|:),0,0) /)<br></div><div><br></div><div>The last two arguments represent the dimension number to operate on for the eof_ts and x2 arrays. In this specific case, you are index subscripting eof_ts from a 2D array to a 1D array, and thus regCoef_n will only see a 1D array and the 1st dimension should be operated on. Finally, you are dimension reordering x2, and you don't really need to do this if you were to use regCoef_n. You just need to indicate the correct dimension to operate on with the last provided argument.</div><div><br></div><div>Hope that all helps. If you have any further questions please respond to the ncl-talk email list.</div><div>Adam </div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Aug 22, 2017 at 2:19 PM, Melanie O' hanoly <span dir="ltr"><<a href="mailto:mel.hanoly@gmail.com" target="_blank">mel.hanoly@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div style="font-size:12.8px"><pre style="white-space:pre-wrap;color:rgb(0,0,0)"><i>Dear NCL users, I just have a little knowledge on NCL.
