This list describe some of the known problems in SEISAN:
|Azimuthal of arrival (h command in MULPLT single trace), channels with orientation code 1 and 2 are handled as N and E. If the orientation of 1 and 2 is off North and East the estimated azimuth will be wrong.
|Particle motion (PartM or P command in MULPLT multi trace) will not work with channels that has orientation code 1 and 2.
|If waveform data from a three component sensor is rotated it is assumed that the response is the same on all three rotated channels (Z,R,T).
| If MULPLT gives the following error:
"–fonts– ERROR: Unable to get font"
on Linux, it means that the default font used in SEISAN is not installed.
The solution is to install the default font -adobe-courier-bold-r-normal–12-120-75-75-m-70-iso8859-1 or to use an other font
Linux users can check which fonts they have installed with the command textttxlsfonts
See FONT under SEISAN.DEF see page .
| AUTOREG crash with the message
textttAt line 356 of file autoreg.for
Fortran runtime error: Bad value during integer read
This is because the waveform filename have characters in the filename where AUTOREG assumes an integer, like:
2019-03-10-1819-M.DATA, solution is to rename file to:
| EEV crash with the message like:
At line 1657 of file tau.for unit = 22, file = IASP91_linux.HED
Fortran runtime error: End of file This is because the computer is not able to read the IASP91 model files. The solution is to first run the program REMODL and then SETBRN, thereafter copy the IASP91_linux.HED and IASP91_linux.TBL to the DAT folder.
| EEV gives lots of message like:
Bad sqrt argument: NaN.
More than150 arrivals found This is because the computer is not reading the IASP91 model files correctly. The solution is to first run the program REMODL and then SETBRN, thereafter copy the IASP91_linux.HED and IASP91_linux.TBL to the DAT folder.
Other known problems are listed in the index.
