Update. It turned out that the error was still different. Further down the
script I had another similar line
t = gmt(@sprintf("filter1d -Fm1 -T%d/%d/1 -E", sampr1, sampr2),
ship_pg)
and was this line that was causing the error (because 'sampr1, sampr2' was
not accepted, only sampr1[1], sampr2[1]) but the error message was very
misleading because it accused the first occurrence of @sprintf()
