## Parsing tabular data with awk issues

I am reposting this since people wanted a little more info and my question was closed, here is an example of what the output looks like, just typical tabular .txt stuff:

asdfsdf sdfsadf sdfsdf  92  83
sdfsdf  ewrwef  dsruh   32  42
sjgho   uhiu    uhgkuh  91  21


In the above, I am trying to just remove all entries where after the third tab it is below 80, and after the 4th it is below 70. So the 4th and 5th columns if viewed in excel must be above 80 and 70 respectively. In this case, only the first row should remain.

(old question)

I am trying to parse a tabular text file generated by Blastp using awk. Previously I have used this somewhat ugly code, because it worked, to go through to the right columns and cull out values below what I wanted.

#!/bin/bash
#$-cwd #$ -pe mpi 16

awk '$4 > 80.0' blastoutput.txt > StepOne.txt awk '$5 > 70.0' StepOne.txt > Culled.txt


Using it on a new blast result however, the file sizes remain at 300k kb with only a slight decrease on step one, and none for two. My best guess is that it is only recognizing a single line from the whole blast output file, and therefore not removing more. I would think maybe it had something to do with Unix/Windows line ends not being recognized as I saw on other answers, but the thing is I haven’t changed the way I’ve generated the blast results and it was working before, so I don’t know why it would all of a sudden change the way tabular results are created.

I’ve also tried using some parsing options I saw in other answers like the following:

perl -lane 'print $_ if ($F[4] >80.0)' blastp_output_8_26.txt > StepOne.txt


but the results seem to be the same.

Does anyone know what I could do to the blastp output file to make it work with my code? I am convinced something is amiss there, but all my attempts to fix it so far have been for naught.

Thanks.

## Integrating TeX into a Java desktop application

Looking to integrate TeX equations in a TeX-agnostic fashion, suitable for either ConTeXt or LaTeX, into a Java-based desktop Markdown editor. The possibilities are numerous, but I’m not sure what approach to take.

JMathTex outputs to MathML, which must be transformed. JEuclid can transform MathML to BufferedImages (not 100% sure). Neither are JDK 14-friendly and may be too slow to render in real-time. I haven’t looked because I read that they didn’t work with Java 9 (without porting effort), much less 14. Also, the licensing isn’t LGPL, which probably won’t work with the MIT licensing.

The NTS library is reported to compile gentle.tex in about 3 seconds. The spin-off project, εχTEX improves upon NTS, but I don’t know to what extent.

Java LaTeX Report requires a TeX engine.

Yet another possibility is to try JavaTex or rework the project using web2java to transpile WEB files into Java files.

JLaTeXMath does an exceptional job at rendering, though investigation would be required to see if it can perform real-time renders, output as SVG, or otherwise determine if it can integrate with FlyingSaucer.

The HTML preview panel uses FlyingSaucer. The SVG documents are rendered using SVG Salamander. If it was possible to go from TeX to SVG, that could work quite handily, architecturally. Some documentation stated FlyingSaucer can also render MathML, but I suspect the doc is wrong. FlyingSaucer doesn’t integrate with JavaScript. For that I’d have to add a JavaScript Engine.

If a JavaScript Engine is necessary, then using KaTeX may be an option.

Still another possibility is the TeX to MathML service. This is written in Java, but the source code is not available anywhere. I’ve reached out to some people involved in the project.

For native speeds, there may be a (cross-platform?) C-based TeX engine that can generate MathML or SVG from a TeX input. If so, it may be possible to integrate with the JNI.

Here’s a demo video of the app, to give you an idea of what is needed:

The goal is to produce real-time rendering of math, ideally in pure Java (no JavaScript).

What approach would you take and what do you see as its benefits and drawbacks?
