Dear Sunix users:
Do you have any advice on the correct use of seg2segy? What am I not understanding? Any words of wisdom would be most helpful. Thanks in advance, Juan
PROBLEM I am having difficulty converting SEG2 formatted files into SEGY and SU files.
INSTRUCTIONS: seg2segy 2.dat 1 > 2.sgy (BAD) segyread tape=2.sgy >2.su (BAD)
suximage < 2.su & (BAD) suximage < 2_clean.su (GOOD)
VISUAL RESULTS Screenshot shows GOOD on left and BAD on right
SYSTEMS and SOFTWARE USED cwp_su_all_44R4 CentOS8 linux box cygwin (64) on Windows10.
FILES ATTACHED 2.dat (a SEG2 file from a Geometrics box) 2.sgy, 2.su 2_clean.su Screenshot in png format of suximage-generated plots.
NOTES: -For reference, I converted a test file (2.dat) successfully from SEG2 to SU format using sioseis under CentOS8 This "GOOD" file is 2_clean.su
-"BAD" means that I am able to obtain a plot which shows amplitudes that seem too large-- with streaks about the middle of the plot(file)
-"BAD" means that I can read the trace header values in HEX, the numbers are correct but that the data values seem too large.
-When I convert from seg2segy I get data value warnings (=0 and < 0), and the data format appears to be in 4-byte integer style.
-I have tried changed "scale" values in seg2segy.c and recompiling but I still get poor results.
