Pasteup determines font sizes automatically by referring the DPI of your X server. If your X server does not tell you a correct DPI, some fonts become too small/big. This is the case often reported on the X server of Mac OS X.
To avoid this trouble, set correct DPI by a command line option --Xdpi. See the following example.
$ pasteup --Xdpi 96
In Pasteup, lag time between the first sample and the shot time is defined by
delrt + tstat + lagb - laga
Check your data.
In the standard SEG-Y and SU format, the delrt is defined as signed short. However, delrt is declared as unsigned short in the Pasteup. If you don't like this declaration, give "-DUNSIGNED_DELRT" flags to the CFLAGS while compiling the Pasteup.
The appropriate scale factor depends on plottining styles in addition to the data itself. Try to use "set scaling factor automatically" function; type M-s or invoke from the "Exec" menu in the console window.
A criteria to determine automatically scale factor is propotinal to the maximum amplitude of the waveform data (after applying amplitude corrections). This criteria can be customized in the Preferences window.
Because Pasteup uses cache system. See the below Cache system FAQ.
This is because of a sort of rounding error.
Each plotting style has the default drawing style. When you change the plotting style, the drawing style is automatically set to the default style. These default styles can be customized in the Preferences window.
Comparing with other plotting software like suximage, Pasteup is (much) slower to draw a section. One of the principal factors is the versatility of Pasteup. In the Pasteup,
These versatility require a lot of computaions and make Pasteup
slow.
Another factor is Tcl/Tk. In the Tcl/Tk, at
first, all the objects are stored in RAM area as vector data, and
then rasterized to the graphic display.
To speed up, try the followings.
Probably you gave invalid values to some parameters; e.g., gave "alphabet" to the distance range or so.
If you have parameter files, try to use them.
$ pasteup -f parameter.dat
However, the easiest way is "to reset" all the parameters to default values. Try,
$ pasteup --noparam
or
$ pasteup --vanilla
Reading large seismic data from a hard disk takes long time. In addition, filtering (including SU filter) process needs more time. To avoid repeating reading and filtering, Pasteup preserves seismic data (after applying filters) in RAM. The preserved seismic data are called cache data.
No, trace length is limited. The trace length in the cache is determined by the parameter extra read length in the Preferences window. When the drawing range is t1 from t2, and the extra read length is dt, the cache range is from t1 - dt to t1 + dt.
The cache system uses the cache data wherever possible.
The cache will be cleared when,
Yes. Seismic data sometimes can be too large to store in the RAM. That is why the Pasteup limit the cache size. The default cache size is 4000 samples/trace and 10000 traces. This limitation indicates the cache system requires 152MB RAM area. If you have enough memory, you can extend these limitations; the cache size is determined when you invoke the Pasteup and cannot be changed on the fly.
# 6000 samples/trace, up to 20000 traces
$ pasteup --maxsample 6000 --maxtrace 20000
Plotting becomes slower, and that's all.
When the required data size is larger than the cache size, pasteup
will give up using cache system.
Yes. invoke Pasteup with --maxtrace 0 option;
$ pasteup --maxtrace 0
If you don't have special reasons, use "Pasteup" format because it is most informative format and we can easily convert it into another formats.
See Formats section.
SU. The developer uses only SU format, therefore more bugs might exist when you use the other formats.
Because SEG-Y format have many dialects, Pasteup probably does not support your SEG-Y dialects. In such a case, convert your SEG-Y data into SU. Probably segyread command in SU is enough.
No, not yet. Use little endian, or big endian SU format even if you use 64bit systems.
To use SU filter, you have to install SU.
In addition, you have to set environmental variable CWPROOT.
You can set the CWPROOT in either of the following:
$ CWPROOT=/path/to/SU pasteup
Possible reasons are,
Position fix and auto picking uses external commands written by FUJIE or Kimihiro Mochizuki.
To use Ray-tracing function, you need an external seismic application "HAMEN" developed by FUJIE.
To use traveltime mapping function, you need an external seismic application "TMM" developed by FUJIE.
Set the install path of these application in the Pasteup. There is two way.
$ ./configure --hamne=/path/to/hamen --tmm=/path/to/tmm
If you are system administrator, choose the former way. Otherwise, choose the latter.
Graph canvas is used the graph widget of BLT. Thus, check the graph widget of the BLT.
BLT has many demo script. Run these demos and check behaviors.
