Dear BUMers,
I tried to perform an "interleaved" acquisition of a ser file, i.e.
acquire few (e.g. 8) scans of each row and repeat the experiment from
the beginning several times. The program for heteronuclear steady state
NOE is enclosed.
The program works, however, after random number of cycles (l5) I receive
a message:
rcuerror: try to write outside file limits on disk
and the data acquired later are not saved to the file.
Thus, the same experiment (ns=8, l4=2, l5=20) breaks up randomly at some
write command in the sequence.
Does anybody know how solve this problem?
With the best wishes,
Jan Lang

; should be attenuated to avoid heating sample
;p1 : f1 channel - 90 degree high power pulse

;VDLIST contains two values:
; very long delay for irradiation (8*T1),
; very short delay (0.001 msec)
;this pulse program produces a ser-file (PARMOD = 2D)
