Claritas plot job include the 4th column(depth) in the velocity table, is there any option present to ovide this coloum in final ouput. only three column (time, vrms, vint) print on plot?

Re: Plots Link to this post

How we plot tie point of line on the plot job. Can we define the Bold fix datum line in elevation graph.

For mapfile and logo file which format is used. i tried .bmp but it gives error. please suggest

Re: Plots Link to this post


tiffrtl utilitiy not cinvert the RGB Tiff file. so for this what we do? second how we create the map file in claritas, if we use the smap utility, and take dump this image is also in RGB colors, and tiffrtl utilitiy not accept it.
Is there any option in plotting modules to control the font style line regular, bold italic etc. Hieghts of font present but when we take the plot the font writing are dim in color.please suggest.

The TOPLABEL module which controls the plotting of the NMO file on a hardcopy plot has no controls for defining how many columns and what to plot in the velocity boxes as in most situations all of the columns are required by the user.

the TOPLABEL module can be used to produce plots containing statics, nmo functions, line intersections, elevation fold etc. You can find more details on what you can plot and how to go about this by searching for TOPLABEL in the Claritas help.

You can convert *.tiff images to *.rtl files which are then easy to include in the plots using the MAPFILE and/or LOGOFILE parameters in the SIDELABEL module. The tiffrtl utility can be used to convert between *.tiff and *.rtl files (and *.rtl to *.tiff files) by typing the following command into a terminal window
tiffrtl 'name of infile' 'name of outfile'
(for greater detail on this utility see section 16.6.3 of the Claritas manual)

Yes unfortunately the RGB format of Tiff file is not yet supported. You can use the unix convert command to convert your *.tiff file to an appropriate format. For example if you type the following into a terminal window
convert -monochrome 'input file' 'output file'
your tiff image will now be black and white and should be acceptable to the tifffrtl utility. You can open the converted image in the Xrtl application to see if the image has been converted correctly. It may be necessary to include a -negate option in the above comand to get the white and black image displayed correctly. The Xrtl application can be opened from the Plotting tab of the Claritas launcher or by typing xrtl in a terminal window (opening in this manner allows more error messages to be viewed). The Xrtl application can also be used to save the *.tiff image as a *.rtl image (in addition to the tiffrtl utility).
There is no option to control the style (bold, italic etc) of the font used in the plot, only the font height can be altered.

I have picked velocity at every 40th cdp when i use this nmo file in TOPLABEL module for ploting, In the tiff file the velocity tables are not at regular cdp intervals(40th cdp).

Is there any option to avoid the depth colum from the velocity Tables and make velocity tables at regular cdp intervals.

Re: Plots Link to this post

There are no user controls in the TOPLABEL module to determine how the tables of the *.nmo file are output on the plot. Hence there is no option to remove the depth column of the velocity table.
I think the TOPLABEL module starts from each end of the input *.nmo file and outputs tables above the corresponding CDP, at a regular interval. This interval is determined by how many tables can physically be displayed along the top of the plot. For example if you have CDPs 200-1080 picked every 40th CDP in your *.nmo file but there is only room for 12 tables to fit along the plot then the following tables will be produced above the corresponding CDPs -200, 280. 360, 440, 520, 600, 680, 760, 840, 920, 1000, 1080. There is simply not enough room to output a table for every 40th CDP, so only every 80th is output. If you instead have CDPs 200:1120/40 then tables would be output at the following CDPs 200, 280. 360, 440, 520, 600, 720, 800, 880, 960, 1040, 1120 giving an irregular distribution.
