Hi! I have some problems importing data from files that look like this:

METAR ESDF 010020Z AUTO 31003KT 230V350 9999NDV NCD 12/08 Q1017 METAR ESDF 010050Z AUTO 24003KT 230V320 9999NDV NCD 12/08 Q1017 METAR ESDF 010120Z AUTO 25003KT 230V350 9999NDV NCD 11/08 Q1017 METAR ESDF 010150Z AUTO 25005KT 230V350 9999NDV NCD 11/08 Q1017 METAR ESDF 010220Z AUTO 24005KT 230V310 9999NDV NCD 11/08 Q1017 METAR ESDF 010250Z AUTO 30003KT 230V350 9999NDV NCD 11/08 Q1017 METAR ESDF 010320Z AUTO VRB02KT 9999NDV NCD 11/08 Q1017 METAR ESDF 010350Z VRB02KT CAVOK 11/08 Q1017 METAR ESDF 010420Z 00000KT CAVOK 12/09 Q1018 METAR ESDF 010450Z 29003KT CAVOK 12/11 Q1018 METAR ESDF 010520Z 30005KT 230V350 CAVOK 13/11 Q1018

The import stops around line 6300 out of 450000. The reason is a linechange in the .txt file that is erroneous. Is there a way of blocking this line and continue with the next instead?

The next step for me is to import a sequence of these files with:

txtFiles = dir('*.txt') numfiles = length(txtFiles); mydata = cell(1, numfiles);

for k = 1:numfiles try mydata{k} = importdata(txtFiles(k).name); catch disp('error') end end

Are there any better way of importing these files?

Thank you!
