Concatenate string from text file
Hi

mY files paths are defined as :


Code:
//sbase = 'D:\data\sample_AMC\fasta_files\';
sbase2 = 'D:\data\sample_AMC\fasta_files\results\';
snameprefix = 'orig_ind';
snameprefix3 = 'results_ind';

...
const string filname = sbase + snameprefix  + snamesuffix;
const string resultsname_ = sbase2 + snameprefix3  + snamesuffix;

This concatenation works perfectly fine when i have to manually defines the samplesnames


However now I have 98 such samples names to work with.This implies I have to keep updating my sbase and sbase2 98 times.

If my sample name changes from sample_AMC to sampleABC_123 then I have to update the path manuallyto
Code:
sbase = 'D:\data\sampleABC_123\fasta_files\';
sbase2 = 'D:\data\sampleABC_123\fasta_files\results\';


In order to make it easier,I saved all my 98 samplename entries in a text file.


text file looks like this
sample_AMC
sampleABC_123
sampeBMC
sampleQWE

Is there a way I could read string entries line by line from a text file using c++ and concatenate it to sbase and sbase2?

ppmtosixel

ppmtosixel(1)						      General Commands Manual						     ppmtosixel(1)

NAME

       ppmtosixel - convert a portable pixmap into DEC sixel format

SYNOPSIS

       ppmtosixel [-raw] [-margin] [ppmfile]

DESCRIPTION

       Reads  a  portable  pixmap  as input.  Produces sixel commands (SIX) as output.	The output is formatted for color printing, e.g. for a DEC
       LJ250 color inkjet printer.

       If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled.  A printer control header and a color assignment table
       begin the SIX file.  Image data is written in a compressed format by default.  A printer control footer ends the image file.

OPTIONS

       -raw   If  specified,  each  pixel  will  be explicitly described in the image file.  If -raw is not specified, output will default to com-
	      pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands.  A raw file is often an order	of  magni-
	      tude larger than a compressed file and prints much slower.

       -margin
	      If  -margin  is not specified, the image will be start at the left margin (of the window, paper, or whatever).  If -margin is speci-
	      fied, a 1.5 inch left margin will offset the image.

PRINTING

       Generally, sixel files must reach the printer unfiltered.  Use the lpr -x option or cat filename > /dev/tty0?.

BUGS

       Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion.  If the original PPM maxval was
       greater	than  100,  rescaling  also reduces the image depth.  While the actual RGB values from the ppm file are more or less retained, the
       color palette of the LJ250 may not match the colors on your screen.  This seems to be a printer limitation.
