Dear NCL helpdesk,<br class="">
<div class=""> <br class="">
I have a question re the <b class="">addfiles</b> function. I am using
this function in order to read data from an ensemble of 101 NetCDF
files - let's say from <i class="">simulation000</i>.<i class="">nc</i> to <i class="">simulation100</i>.<i class="">nc</i>.
<br class="">
<br class="">
My question is, what is the order the files are read with? Can I
assume is from 000 to 100 if I have <br class="">
<br class="">
<pre style="margin: 0px; padding: 0px; font-size: 13.3333px; line-height: 16px; font-family: courier; border-style: solid; border-width: 0px 0px 15px; border-color: transparent; text-indent: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-position: normal; font-variant-caps: normal; font-variant-numeric: normal; font-variant-alternates: normal; font-variant-east-asian: normal; font-weight: normal; letter-spacing: normal; text-align: left; text-transform: none; word-spacing: 0px; background-color: rgb(255, 255, 255);" class=""> all_files = <a href="http://www.ncl.ucar.edu/Document/Functions/Built-in/systemfunc.shtml" style="margin:0px;padding:0px;text-decoration:none;color:rgb(133,45,133);font-family:verdana,sans-serif;font-weight:normal" target="_blank" class=""><strong style="margin:0px;padding:0px" class="">systemfunc</strong></a> ("ls ./simulation*.nc")
fall = <strong style="margin:0px;padding:0px" class="">addfiles</strong> (all_files, "r") </pre>
I ask this because I had a missing value error for the last file -
but <a href="http://simulation100.nc/" target="_blank" class="">simulation100.nc</a> file seems to be ok. Do you have any clue why
this could happen? <br class="">
<br class="">
Thank you for your help,<br class="">
<br class="">
Best regards<br class="">
