[GRASSLIST:1650] problem importing GMT grd files

[Zbigniew Perski]

Hi all,

I can not import grd files type 1 (converted with gmtreformat to format 
1 GMT) to Grass (5.0.2, running on i686 and i686 compiled from source on 
those machines with Linux - kernel 2.4.22).
I am trying the r.in.bin -fh command and 4-byte

The GRD file:
grdinfo coherence.bin=1
coherence.bin: Title:
coherence.bin: Command: xyz2grd coh.xyz -Gcoherence.grd -I1c 
-R7:42:13/8:41:26/49:35:29/50:12:17 -V
coherence.bin: Remark:
coherence.bin: Normal node registration used
coherence.bin: grdfile format # 1
coherence.bin: x_min: 7.70361 x_max: 8.69056 x_inc: 0.000277778 units: 
user_x_unit nx: 3554
coherence.bin: y_min: 49.5914 y_max: 50.2047 y_inc: 0.000277778 units: 
user_y_unit ny: 2209
coherence.bin: z_min: 0.0565573 z_max: 0.991879 units: user_z_unit
coherence.bin: scale_factor: 1 add_offset: 0

And Grass r.info:
