Why receive error message "Could not find variable or group 'Bandl' in file."

When I dispaly information abut my netcdf file (1982 January average sst) it dispalys the variable "Bandl" which must be the sst data. But when I want to access that variable to through "ncinfo" as shown below I receive an error message "Could not find variable or group 'Bandl' in file." Why is that?

Error using internal.matlab.imagesci.nc/getGroupAndVarid

Could not find variable or group 'Bandl' in file.

Error in internal.matlab.imagesci.nc/info (line 979)

[gid, varid] = getGroupAndVarid(this, location);

Error in ncinfo (line 98)

info = ncObj.info(location);

Figured it out thanks.

Answer 2

[Walter Roberson]

You are asking to access Bandl with the final character being lower-case L . The variable in the file is Band1 with the final character being the number 1.

Thank you very much Walter.
