Maybe filename and dirname have to be identical
1.2 ENSO & SOI (Southern Oscillation Index) Equatorial (Nino) SST
There are several options depending on Nino-regions and analysis type:

1.3 Solar Cycles & Solar Flux
1.3.1 400 years Solar Flux
Original sources: Lockwood, M., Owens, M.J., Barnard, L. (2014) JGR,
Centennial variations in sunspot number, open solar flux and streamer belt width.
Data available at: /asl/s1/chepplew/data/atmosSci/Solar/JGR_Lockwood_OSF3_supplementarydata.txt
with matlab reader: osf_reader.m also in that directory.
And detailed solar wind variations (speed, magnetic field, proton density and
proton temperature at:
/asl/s1/chepplew/data/atmosSci/Solar/srep41548-s{2,3,4,5}.txt With matlab reader
srep_reader.m also in that directory.
