Hi,I'm trying to image a VLBA dataset that I have already calibrated. However, when trying to run imagr for the fluxcal (or any of the sources) I get the following message:......localh> IMAGR1: UVWAIT U, V, NR, WT <= 0 2 256 5223698 0.0000E+00localh> IMAGR1: UVWAIT U, V, NR, WT <= 0 3 256 5224209 0.0000E+00localh> IMAGR1: UVWAIT U, V, NR, WT <= 0 1 255 5223186 0.0000E+00localh> IMAGR1: UVWAIT: Sum of weights in 1.606E+01 and out 0.000E+00localh> IMAGR1: UVWAIT: Noise is increased by a factor 0.000 due to weightinglocalh> IMAGR1: UVWAIT: Average summed weight 0.000E+00 over 4072. vislocalh> IMAGR1: Create 1330+071 .IBM001. 1 (MA) on disk 1 cno 8localh> IMAGR1: Create 1330+071 .ICL001. 1 (MA) on disk 1 cno 9localh> IMAGR1: GRDFLT: X and Y convolution type = SPHEROIDALlocalh> IMAGR1: GRDFLT: X and Y parms = 3.0000 1.0000localh> IMAGR1: GRDFLT: convolution function sampled every 1/100 of a celllocalh> IMAGR1: GRDMEM: Ave 2 Channels; 4.476000E+09 to 7.696000E+09 Hzlocalh> IMAGR1: Field 1 Sum of gridding weights = 0.000000E+00localh> IMAGR1: Field 1 Beam min = 100.0 Exa Jy, max = 0.0 Jylocalh> IMAGR1: FITBM: SOLUTION FOR RESTORING BEAM FAILEDlocalh> IMAGR1: Fit Gaussian FWHM = 108.764 x 108.764 Microarcsec, PA= 45.0localh> IMAGR1: BEAM HISTOGRAM PATHOLOGICAL - DEALING WITH ITlocalh> IMAGR1: CLBHIS: minimum component 0.000 of current peaklocalh> IMAGR1: Field 1 min = 100.0 Exa Jy,max = 0.0 Jylocalh> IMAGR1: CDECID: Will load every 12 th. residuallocalh> IMAGR1: BGC Clean: using 103 cell beam + residuals > 4.95 Kilo Jylocalh> IMAGR1: 1150 Residual map points loadedlocalh> IMAGR1: CLACLN: ILLEGAL FIELD NUMBER402, NOT 1- 1localh> IMAGR1: CLACLN: FINDING COMPONENTlocalh> IMAGR1: CLNCYC: ERROR CLEANING CLEAN process objectlocalh> IMAGR1: CLNUV1 : ERROR CLEANING CLEAN process objectlocalh> IMAGR1: CLNUV : ERROR CLEANING CLEAN process objectlocalh> IMAGR1: Deleting UV work file:localh> IMAGR1: Destroyed 1 extension files of type ANlocalh> IMAGR1: Destroyed 1 extension files of type FQlocalh> IMAGR1: Destroyed UV image file: catno= 7 disk= 1localh> IMAGR1: Purports to die of UNNATURAL causesI've tried modifying the cellsize, image size etc, but with no luck. I would be very thankful if you could let me  know what's the problem. The .SPLIT data look fine in uvplt and I have 10 antennas. It's C-band.Thanks,Mar
